Use the chemical reactions shown below to answer the following question.
IO3- (aq) + 5 I- (aq) + 6 H+ (aq) → 3 I2 (aq, brown/yellow) + 3 H2O (l)
I2 (aq, brown/yellow) + 2 S2O32- (aq) → 2 I- (aq, colorless) + S4O62- (aq)
a) What is the stoichiometric relationship between IO3- and I2?
A certain bleach solution is known to be 5.25% NaClO by mass and have a density of 1.084 g/mL.
a) What is the molar concentration (i.e., molarity) of NaClO in this bleach solution?
b) What would be the molar concentration of NaClO if 90.0 mL of water were added to a 10.0 mL sample of the bleach?
