I would like to ask about sodium hypochlorite

Why is sodium hypochlorite the most potent oxidizing agent under acidic conditions
This post was last edited by qugd on 2017-1-10 at 16:23. Under acidic conditions, the oxidizing power of sodium hypochlorite is related to the concentration of hydrogen ions in the system; the hydrogen ion concentration is taken into account in the equation for its oxidation potential. OCl- + 2H+ ----> Cl- + H2O. The expression for the oxidation potential in terms of hydrogen ion concentration can be simplified to E = E0 + Alg(H+)2 = E0 + 2Alg(H+). However, the redox potential of some substances is independent of acid concentration, such as iron ions.
You speak so professionally; I understand 40% of it. Thank you so much
Hello, it is hypochlorite that reflects oxidative capacity; under acidic conditions, it tends to hydrolyze to form hypochlorous acid； Alkaline stability, inhibits hydrolysis. The oxidizing power of hypochlorous acid is greater than that of sodium hypochlorite. What is it that reflects the oxidation capacity? I thought that the amount of hypochlorite ions determined the level of oxidizing power? So I’ve been wondering why it has such strong acidity. I read your message
Based on that reaction equation, hydrogen ions are involved in this redox reaction; both hydrogen ions and hypochlorite ions are reactants. A high concentration of these reactants promotes the reaction to proceed in the direction of forming products. Therefore, as acidity increases, oxidizing power also increases, making it easier for the reaction to proceed in the forward direction. If you haven’t studied some of the concepts in physical chemistry, it might be a bit abstract to understand.
{:3_54:} A hero needs three helpers; hydrogen ions help, while hydroxide ions hinder. Write down the reaction equation by yourself; an increase in the concentration on the left side of the equation facilitates the reaction, while a decrease does the opposite. .
Is the oxidizing power of chloride ions greater than that of hypochlorite ions?
I don’t understand what determines a high oxidation capacity; if there is less reaction with hypochlorite, does that still mean it has a strong oxidation capacity? Is hypochlorite related to the strength of oxidation in reactions?
I still don’t understand – isn’t it the hypochlorite ion that determines the strength of oxidation capacity? More means strong oxidation capacity, while less means weak oxidation capacity
You should read books; right now it’s not a matter of distinguishing right from wrong, as you haven’t even established a solid foundation yet. . .
