Assume 100 g of bleach solution:
mass NaOCl = 5.25 g
molar mass NaOCl = 74.44 g/mol
density = 1 g/mL
moles NaOCl = 0.07052 mol
Calculate the molarity of the bleach solution:
molarity = 0.7052 M
500.0 mL of a pH = 10.26 solution solution:
Calculate the concentration of NaOCl:
NaOCl → Na+ + OCl-
OCl- + H2O → HOCl + OH-
A solution of household bleach contains 5.25% sodium hypochlorite, NaOCl, by mass. Assuming that the density of bleach is the same as water, calculate the volume (in mL) of household bleach that should be diluted with water to make 500.0 mL of a pH = 10.26 solution.
