For the operation of a home swimming pool, it is necessary to control the pH of the pool water. Generally, it is maintained at about pH = 7.2. It is desirable to lower the pH of the water in a 20,000-gal pool from 7.8 to 7.2. What volume of an aqueous solution that is 30.0% HCl, by weight (d = 1.15 g/mL), is required for this purpose?
