Question

when clothes have stains, bleach may be added to the wash to react with the soil and make the stains colorless. the bleach solution is prepared by bubbling chlorine gas into a solution of sodium hydroxide to produce a soultion of sodium hypochlorite, sodium chloide and water. one brand of bleach contains 5.25% sodium hypochlorite by mass with a density of 1.08 g/ml.

a) what is the formular and molar mass of sodium hypochlorite?

b) draw the lewis structure for the hypochloitire ion.

c) how many hypochlorite ions are present in 1.00 gal of blech solution?

d) write the balanced chemical equation for the preperation of bleach.

e) how many grams of NaOH are required to produce the sodium hypochlotire for 1.00 gal of bleach?

f) if 165 g of Cl2 is passes through a solution containing 275 g of NaOH and 162 g of sodium hypochlorite is produced, what is the percent yield of sodium hypochlorite for the reaction ?
