A common method used in manufacturing sodium hypochlorite bleach is by the reaction

Cl 2 + NaOH → NaCl + NaOCl + H2O

Chlorine gas is bubbled through an aqueous solution of sodium hydroxide, after which the desired
product is separated from the sodium chloride (a by-product of the reaction). A water-NaOH solution
that contains 1145 lb of pure NaOH is reacted with 851 lb of gaseous chlorine. The NaOCl formed
weighs 618 lb.
a) What was the limiting reactant?
b) What was the percentage excess of the excess reactant used?
c) What is the degree of completion of the reaction, expressed as the moles of NaOCl formed to the
moles of NaOCl that would have formed if the reaction had gone to completion?
d) What is the % yield of NaOCl per amount of chlorine used (on a weight basis)?

3) A common method used in manufacturing sodium hypochlorite bleach is by the reaction
a, + NaOH → NaCl + NaOCI + H,0
Chlorine gas is bubbled through an aqueous solution of sodium hydroxide, after which the desired
product is separated from the sodium chloride (a by-product of the reaction). A water-NaOH solution
that contains 1145 Ib of pure NaOH is reacted with 851 Ib of gaseous chlorine. The NaOCl formed
weighs 618 Ib.
a) What was the limiting reactant?
b) What was the percentage excess of the excess reactant used?
c) What is the degree of completion of the reaction, expressed as the moles of NaOCI formed to the
moles of NaOCI that would have formed if the reaction had gone to completion?
d) What is the % yield of NaOCI per amount of chlorine used (on a weight basis)?
