commercial bleach contains 5.25% sodium hypochlorite (NaOCl) by mass
density = 1.08 g/mL
assume 100 g solution:
mass NaOCl = 5.25 g
molar mass NaOCl = 74.44 g
Calculate moles of the hypochlorite ion, OCl-:
NaOCl → Na+ + OCl-
moles OCl- = 0.07052 mol
Calculate volume (in L) of solution:
volume = 0.0926 L
Calculate molarity of the solution:
Calculate the molarity of hypochlorite ion when 1.00 mL of commercial bleach is added to 25.00 mL of dye solution.
