when negative ion of Cl increased as a result, the pH value and the voltage was increased also.
Redox reaction: HOCl (aq) + H+ + 2e- → Cl-(aq) + H2O
We can find concentration of HOCl from [HOCl] = (6/52.5) (x/1000) (1000/(1000+x))
Determine X is bleach add, 6 is concentration of bleach, and 52.5 is mass of HOCl
