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. Read more exciting novels for free
The chemical equation of the reaction between carboric acid and alkalium
The chemical equation for the reaction between carboric acid and an alkali-like substance (using the example of soda ash) under heating conditions is: CO(NH2 <2>) 2 + NaCO(NH2 <2>) 2 + 2 H <2> O. The resulting carboric acid is an organic salt that can be widely used in medicine, agriculture, and other fields. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation for preparing concentrated sulfuric acid and nitrogen gas
Based on context alone The concentrated sulfuric acid could not be used for the preparation of hydrogen. Because hydrogen is an basic gas, concentrated sulfuric acid is volatile and acidic. When the two meet, a reaction will occur: <anno data-annotation-id ="cdf10000 - 4c00 - 4c10 - 4c10-a100-a11111110000"></anno>(the reaction phenomenon is to produce a large amount of white smoke), rather than being used to prepare hydrogen. The laboratory usually uses a solid mixture of lithium monium and lithium monium to heat up to prepare hydrogen. The reaction equation is [2NH4] Cl2 + CaCl2][2][3][4][4][5][6][7][8][8][9][9][ CaCl_{2}+2H_{2}O + 2NH_{3}\uparrow\)。 <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>

Acid and Metal Reaction Color
Different metals may react with acid to produce different colors: - The reaction between the dilute sulfuric acid and the dilute sulfuric acid produced a large number of bubbles. The chemical equation was: Mn +2HQ = Mn Cl2 + Mn Cl2, Mn + Mn Cl2 = Mn Cl2 + Mn Cl2 + Mn - The reaction between the two metals was intense and produced a large number of bubbles. The chemical equation was as follows: Mn +2HQ = Mn Cl2 + Mn Cl2, Mn + Mn Cl2 = Mn Cl2 + Mn Cl2 + Mn Cl2 = Mn Cl2 + Mn Cl2 = Mn Cl2 + Mn Cl2 + Mn Cl2 = Mn Cl2 + Mn Cl2 = Mn Cl2 + Mn Cl2 + Mn Cl2 = Mn Cl - When iron reacted with diluted sulfuric acid or sulfuric acid, a small amount of bubbles appeared on the surface of the nail. At the same time, the solution turned light green because of the formation of iron sulfuric acid or iron chloride.The reaction equation was: FeCl2 <2>+ H <2>, FeCl2 <2>= FeCl2 <2>+ H <2>, FeCl2 <2>= FeCl2 <2>= FeCl2 <2>+ H <2>. - Copper does not react with dilute sulfuric acid or dilute sulfuric acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Cyclohexylbenzen and Acid Permanganate?
Cyclohexyl-benz-lene reacted with acidic potassium permanganate. Cyclohexylbenzen was a homolog of benzen. When the carbon atom on the benzen ring had hydrogen, it could be oxided by the solution of potassium permanganate. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Barium Cyanate and Acid
The reaction between Ba(Ce) 2 and sulfuric acid (HQ) will produce hydrogen cyanide (HQ) gas. The reaction equation is Ba(Ce) 2 + 2HQ = BaCl2 + 2HQ. Barium cyanide is an extremely toxic substance. When exposed to high heat or acid, it will produce a highly toxic cyanide gas. When operating a reaction involving potassium cyanide, safety regulations must be strictly adhered to. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What else can the reaction of sulfuric acid and sulfuric acid do?
The reaction of the two could be used in the laboratory to produce nitrogen.((NH4) 2SO4 + 2NaOx = 2NH3 ^+ Na2SO4 + 2H2O), the nitrogen gas can be used for many purposes, such as the catalyst of the nitrogen dioxide.(4NH3 + 5O2 = 4NO +6H2O) and other reactions;<(NH4) 2SO4>> can be used for double decomposition reaction with table salt to produce aminium chlorideand react with aluminum sulfuric acid to produce aminium aluminum. It can be used together with Boric acid to produce fire-resistant materials. Adding it to plating solution can increase the electrical conductivity. It is also a catalyst for food maroon color. It is also a nitrogen source for cultivating yeast in the production of fresh yeast. It is also used for dyeing auxiliary agents for acid dye and leather deashing agent. It is also used in beer brewing, chemical reagents, and battery production. There were also applications such as mining rare earths (about 5 tons of lithium sulfuric acid was needed for each ton of rare earth ore), and so on. The use of lithium sulfuric acid could be used to make soap, improve soil (improve soil with lime powder, and use organic fertilizers such as lithium sulfuric acid and lithium chlorideto alkalize the soil), etc. After the two reacted, they could play a certain role in these related industrial production or reaction processes. For example, in the production process with the participation of lithium sulfuric acid, if the reaction needed to participate in the reaction, the reaction of lithium sulfuric acid and lithium sulfuric acid could be used to produce lithium sulfuric acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
