###### FREE Expert Solution

We are asked to calculate the molarity of hypochlorite ion in a commercial bleach solution.

5.25% sodium hypochlorite by mass and the density of the solution is 1.08g/mL.

sodium hypochlorite → NaOCl

Assume 100 g solution → 5.25 g NaOCl

Calculate moles OCl :

Molar mass NaOCl = 74.44 g/mol

mol OCl = 0.071 mol OCl

Calculate volume:

= 0.093 L
