Problem- An overly efficient student simultaneously prepared two titration mixtures, consisting of diluted bleaching solution, KI solution, and HCI solution. The student found that data from the two titrations yielded significantly different percents NaOCI in the commercial bleaching solution. Which determination would give the higher % NaOCI? Briefly explain.
Here is the problem which I am struggling on, please help me!
