Reaction equation of acid and acid base indicator
The chemical equation of the reaction between acid and indicator: KHIn/(H+)=(In-)/(HIn)=a/(a-c). Using litmus as an example, the equilibrium of the ions was HIn = In- + H+. However, it should be noted that the acid and base indicator will change color when it meets an acidic or basic solution. The actual color change is the acid and base indicator, not the solution itself. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Acid base reaction carbon dioxide
Acid and base reactions can produce carbon dioxide. For example, the reaction of soda ash (Na_{2}CO_{3}) with an acid (such as sulfuric acid,<anno data-annotation-id ="00000000 - 4110 - 4410-a110-a1100111000"> ClCl3 </anno>) will produce carbon dioxide. The reaction equation is <anno data-annotation-id ="2c3cd00 - 4c50 - 4c50 - 4c50 - 9c51100000000"> Na_{2}CO_{3}+2Cl3 + 2Cl3 = 2NaCl4 + H_{2}O+ CO2}</anno></anno>. In the laboratory, diluted sulfuric acid reacted with marble (the main component of calcium dioxide) to produce carbon dioxide. The chemical equation was [CaCO3]+2HQ = CaCl2 + H2O + CO2]. The reaction between edible alkali-based and acid could produce carbon dioxide. When the dough fermented too much and had a sour taste, edible alkali-based could neutralize the sour taste. At the same time, the reaction between alkali-based and acid produced carbon dioxide to make the dough more fluffy and puffed. Baking soda (acidic) could also produce carbon dioxide when it reacted with acidic substances. For example, when white vinegar (acidic) and baking soda were mixed at home, they would react to produce carbon dioxide, which could be used for simple scientific experiments. The carbon dioxide produced by the reaction could make the balloon bulge, and the gas could extinguish the flame. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the phenomenon of acid and base neutralizing reaction?
The reaction of strong acid and strong base generally did not have obvious experimental phenomena (such as settling, bubbles, dissolving and disappearing of indissolvable substances, color change of solution, etc.). However, in daily life, there were many applications of the alkali-base neutralizing reaction that reflected certain phenomena. For example, when the alkali-base neutralizing reaction was used to treat gastric acid, the symptoms of hypergastric acid (such as acid acid reversal and burning sensation in the stomach) would be alleviated; When slaked lime was used to alleviate the acidic soil, the state of the acidic soil would be improved, which was conducive to plant growth; When vinegar was used to remove scale, the scale would be dissolved; After mosquito bites, applying soap water could reduce redness, swelling, pain, itching and other symptoms. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is the reaction between sulfuric acid and base poisonous?
The reaction between sulfuric acid and base would release a lot of heat, but the reaction itself did not produce toxic substances. However, during the reaction, if the concentration of sulfuric acid is high enough, it is highly corrosive and may cause dangerous situations such as chemical burns. If the reaction is carried out in an uncontrollable environment, the heat generated by the reaction may cause other dangers, such as releasing toxic substances from the surrounding substances or causing the sulfuric acid to evaporate and produce acid mist. Inhaling the acid mist may cause acute poisoning, eye inflammation, burning sensation in the nasal and oral membranes, epistax, gum bleeding, tracheitis, etc. Therefore, the reaction between the acid and the base needed to be carried out in a controlled environment (such as a laboratory). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of carbon dioxide with acid, base and water
1. **二氧化碳与碱的反应** - 二氧化碳能与可溶性碱反应，产物一般是碳酸盐。例如二氧化碳与氢氧化钠反应：当二氧化碳少量时，\(2NaOH+CO_{2}=Na_{2}CO_{3}+H_{2}O\);二氧化碳与氢氧化钙反应\(Ca(OH)_{2}+CO_{2}=CaCO_{3}+H_{2}O\)。不过并不是所有的碱都能和二氧化碳反应，只有可溶性碱能与二氧化碳发生反应。 2. **二氧化碳与酸的反应** - 二氧化碳不与酸反应，从酸碱性角度看，酸和酸不反应，并且二氧化碳既没有强氧化性也没有强还原性，所以和氧化/还原性酸也不反应。 3. **二氧化碳与水的反应** - 二氧化碳遇到水时发生化学变化，产生碳酸，反应方程式为\(CO_{2}+H_{2}O = H_{2}CO_{3}\)，但碳酸不稳定，受热易分解，\(H_{2}CO_{3}\triangleq CO_{2}\uparrow+H_{2}O\)。 <a href="/?from=ask_words" style="color:red" target="_blank">点击前往免费阅读更多精彩小说</a>
Does the acid and base reaction produce water?
In the theory of acid and base, the essence of the acid and base reaction was the formation of water by the formation of H and the formation of water by the formation of H. However, from the broad concept of the acid base reaction, the neutralizing reaction between acid and base in the acid base theory was a process of the transfer of the atom. In this case, water was not necessarily formed. For example, the reaction between acid and base in a non-water system did not necessarily produce water. Therefore, it was wrong to say that the acid and base reaction must produce water. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction conditions of metals and acid and base solutions
1. ** Reaction conditions of metals and acid ** - In the sequence of metal activity, the metal in front of hydrogen can replace the hydrogen in the acid to form hydrogen. - The acid in the reagent could not be an oxiding acid such as HNO3 or concentrated H2SO4. 2. ** Reaction conditions of metals and alkalium **: Generally, active metals (such as aluminum) react with alkalium, such as the reaction of aluminum with a solution of soda. During the reaction, the aluminum must have a certain chemical activity, and the concentration of the alkalium solution must reach a certain concentration (reaction equation: <<2A1>+<2H2O>>=<2NaAlO2>+<3H2O>>>). However, the reaction of common metals with alkalium is relatively rare compared to the reaction of metals with acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Anhydrous aluminum chloride-acid or base reaction
According to Lewis 'theory of acid and base, any molecules, ions, or groups that can accept an electron pair are called acid, and any molecules, ions, or groups that can donate an electron pair are called bases. Anhydrous aluminum chloridecould be used as a Lewis acid catalyst, so it was an acid reaction, not a base reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between acid and base must be a neutralizing reaction, right? Why?
The reaction between acid and base was not necessarily a neutralizing reaction. Neutralization reaction was defined as the reaction between acid and base to form salt and water, but the reaction to form salt and water was not necessarily a neutralizing reaction. For example, the reaction between some oxides could also form salt and water, but it was not a reaction between acid and base. Therefore, it could not be determined that the reaction between acid and base was a neutralizing reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the conditions for the reaction of organic matter with acid and base?
The conditions for different organic substances to react with acid and base were different: - When the organic matter is a ether, it can react with a base. - Carboxic acid can react with bases. - In the water solution, the halalocarbon would react with the alkali-like water, and in the alcohol solution, it would react with the alkali-like alcohol. - Esters can be subjected to the reaction of acid or base. Under base conditions, the reaction is slow when not heated, but the reaction is accelerated when heated. Under acid conditions, it is usually diluted acid and the reaction occurs when heated. - An organic compound with both acid and base functional groups (such as an acid, a protein, etc.) can react with both acid and base. - The silver mirror reaction can occur in the presence of organic substances (such as alkyls) that contain " - The dehydration reaction of alcohol required concentrated sulfuric acid as a catalyst and an absorbing agent, and the reaction was carried out under acidic conditions. - Oils and fats are ester substances, which can undergo a water decomposition reaction under acid or base conditions. - The acidic organic matter and the basic organic matter would undergo a neutralizing reaction. The basic organic matter generally had the characteristic group of an amine group, while the acidic organic matter generally contained a Carboxyl group or a alcoholic group. Some of them only had a alcoholic group, but with the acidic group, they could undergo a neutralizing reaction with other substances (acid and base exchange components to form salt and water). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
