1. The problem statement, all variables and given/known data An active ingredient in common household bleach solutions is most likely to be which of the following? A)NaCl B)NaClO C)NaHCO3 D)Na2SO4 E)HC2H3O2 2. Relevant equations - 3. The attempt at a solution So bleach is a cleaning agent and most cleaning agents are basic so then the salt needs to be a basic salt (so formed from a weak acid). This eliminates A and D. E won't be it cause it is a weak acid. This leaves B and C. The weak acid is hypochlorous acid and carbonic acid respectively. But I can't choose between the 2. I only found out by googling bleach. Is there a way to solve it or do you just need to know that bleach contains sodium hypochlorite?
