Concentration of hypochlorite in buret solution : 0.004984 M/L Concentration of hypochlorite bleach in the ORIGINAL solution was diluted 50:1 giving us: 0.2492 M/L Question 1: Active ingredient in household bleach is NaOCl. Find % concentration (w/v) in household bleach. (Mass of NaOCl per mL of solution) *Atomic mass of NaOCl = 74.44217 Question 2: Using the % w/v of NaOCl on the bleach bottle, calculate the percent error in experiment.
