What is the molarity of NaOCL in a solution of bleach if 10.00mL requires 22.35mL of 0.0291 M Na2S2O4 to reach the endpoint.

Answer 1

There must be more to it than that. NaOCl can't be titrated with thiosulfate, at least not when I went to school. The USUAL process is to treat a solution of bleach with KI and titrate the liberated I2 with thiosulfate.
