Question

Household bleach is prepared by dissolving chlorine in water.

 Cl2 (g) + H2O  « H+ (aq)  +  Cl- (aq)  +  HOCl

 Ka for HOCl is 3.2 x10-8  . How much chlorine must be dissolved in one liter of water so that the pH of the solution is 1.19?

 

Caproic acid HC6H11O2   is found in coconut oil and is used in making artificial flavors. A solution is made by dissolving 0.450mol of caproic acid in enough water to make 2.0L of solution. The solution has [H+] 1.7 x 10-3 M. what is Ka for caproic acid?

 

Phenol, once known as carbolic acid, HC6H5O, is a weak acid. It was one of the first antiseptics used by Lister. Its Ka is 1.1 x 10-10. A solution of phenol is prepared by dissolving 14.5g of phenol in enough water to make 892mL of solution. For this solution, calculate the pH
