In the reaction of the primary battery of the reaction between the hydrogen ions and the hydrogen ions: 1. ** Negative reaction ** - The loss of electrons in the reaction of the oxygen is expressed by the reaction equation: [Mn- 2e^-]. This was because the metal activity of the metal was strong. In the reaction, its valency increased and it was oxided, so it was a negative reaction. 2. ** Positive reaction ** - The hydrogen ions in the solution get electrons at the positive pole and undergo a reduction reaction. The reaction equation is [2H^++2e ^-]. The hydrogen ions gained electrons, and their valency was reduced. This was why it was a positive reaction. 3. ** Total battery reaction ** - Adding up the positive and negative reactions, the total reaction equation of the battery was obtained. This reaction represented the conversion relationship of the substances in the entire primary battery reaction process. Read more exciting novels for free
Under acidic conditions, manganate (Mn O42-) will react with hydrogen dioxide (H2O2). The ion equation is: Mn O42- +2H2O2 + 4H + = Mn2+ +4H2O +2O2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The hydrogen ions (H) do not react with carbon dioxide (CO2). When carbon dioxide is dissolved in water, it will form carbolic acid (H Chi CO). Carbonic acid is a weak dibasic acid, and its equation is H Chi CO H + HCO, HCOH + CO2. It can produce hydrogen ions, so it will not react with hydrogen ions. If it can react with hydrogen ions, then its equation will not work. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
铝离子(Al³⁺)与氢氧化钾(KOH)反应分以下情况: 1. 当氢氧化钾少量时: - 化学方程式为:\(AlCl_{3}+3KOH = Al(OH)_{3}\downarrow+3KCl\)(以氯化铝为例,铝离子在溶液中,这里假设为氯化铝溶液),离子方程式为\(Al^{3 + }+3OH^{-}=Al(OH)_{3}\downarrow\)。 2. 当氢氧化钾过量时: - 首先发生\(AlCl_{3}+3KOH = Al(OH)_{3}\downarrow+3KCl\),然后生成的氢氧化铝继续与氢氧化钾反应,化学方程式为\(Al(OH)_{3}+KOH = KAlO_{2}+2H_{2}O\),总反应方程式为\(AlCl_{3}+4KOH = KAlO_{2}+3KCl + 2H_{2}O\),离子方程式为\(Al^{3 + }+4OH^{-}=AlO_{2}^{-}+2H_{2}O\)。 <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>
The chemical equation of the reaction between calcium hydrogen and sulfuric acid is [2HNO_{3}+ Ka (SH)_{2}= Ka (NO_{3})_{2}+2H_2}O]. Because both calcium hydrogen and sulfuric acid were strong ions, most of them existed in the form of ions in the solution. The ion equation of the reaction was H^{+}+ SH ^{-}=H_{2}O). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

First of all, silver carbonates (Ag2 CO2) were difficult to dissolve, so the chemical formula should be written in the ion equation. The chemical formula for the weak solute, NH2·H2 O, should also be written in the ion equation. The reaction produced (AG(NH2))<2> CO2 <2>, which was a complex compound and also a difficult ionizer. The chemical formula was also written. Because the substances involved in the reaction before and after the reaction could not be disassembled into the form of ions, the ion equation of the reaction was the same as the chemical equation, and there was no change, that is, AgCO + 2NH·H O == (AgNH) CO2 + 2H O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction of carbon dioxide and water first forms carbolic acid (\(CO Ü + H Ü O = H Ü CO\)), and the carbolic acid is further ionised to produce hydrogen carbonate-like ions (\(H Ü CO H + HCO\).
