Homework Help: chemistry

Posted by joe on Tuesday, October 9, 2012 at 6:08pm.

A home swimming pool is disinfected by the daily addition of 0.50 gal (1 gal = 3.785 L) of a "chlorine" solution–NaOCl in NaOH(aq). To maintain the proper acidity in the pool, the NaOH(aq) in the "chlorine" solution must be neutralized. By experiment it is found that about 220 mL of an HCl(aq) solution that is 31.4% HCl by mass (d = 1.16 g/mL) is required to neutralize 0.50 gal of the "chlorine" solution. What is the [OH–] of the "chlorine" solution?
