im takign AP CHEM and i love the course, but we did this one lab. i did the math and came up with the coefficients with the reactants. i'm supposed to compare it to the actual equation, but i can't find it anywhere. the lab included mixing a solution of hypochlorite ions and a solution of thiosulfate ions in a hydroxide solution. well...the hypochlorite and thiosulfate are attached to sodium, but she said not to include those at all in our equations. this is what i have:(adsbygoogle = window.adsbygoogle || []).push({});

.5M solution OCl- = x/.035L

x = .0175 mol OCl-

.5M solution S2O3- = x/.015L

x = .0075 mol S2O3-

so i ratioed the moles and got a 2 OCl : 1 S2O3 .

now all i have to do is find the actual balanced equation and compare it...but i have no clue what the actual equation was and my teacher said to find it online. i searched and searched, but have ended up with nothing. i tried to come up with my own equation which fits this ratio and that is:

2OCl + S2O3 + 6OH --> Cl2 + 2SO4 + 3H2O

this equation matches my ratio that i got, but she said that our ratios may be wrong and to just find the actual equations online because we haven't gotten into redox yet. anyway, all or any help would be greatly appreciated.
