Phenol (CoH5OH) is a weak acid used as a general disinfectant and in the manufacture of plastics. Calculate the concentrations of all species present (H", C6H50, C6H5OH, and OH) and the pH in a 0.386 M solution of C6H5OH (Ka = 2.25 x 10-8). Show your work and write your answers to the correct number of significant figures. C6 H5 OH = C6 H;O¯ + H+

Find [OH+], [OH-] and the pH of the following solutions. (a) 30.0 mL of a 0.216 M solution of HCI diluted with enough water to make 125 mL of solution. (b) A solution made by dissolving 275 mL of HBr gas at 25C and 1.00 atm in enough water to make 475 mL of solution. Assume that all the HBr dissolves in water.
Two students were asked to determine the Kb of an unknown base. They were given a bottle with a solution in it. The bottle was labeled aqueous solution of a monoprotic strong acid. They were also given a pH meter, a buret, and an appropriate indicator. They reported the following data: volume of acid required for neutralization = 21.0 mL pH after 7.00 mL of strong acid added = 8.95 Use the students' data to determme the Kb of the unknown base.

Papaverine hydrochloride (abbreviated papH+Cl; molar mass = 378.85 g/mol) is a drug that belongs to a group of medicines called vasodilators, which cause blood vessels to expand, thereby increasing blood flow. This drug is the conjugate acid of the weak base papaverine (abbreviated pap; Kb = 8.33 109 at 35.0C). Calculate the pH of a 30.0-mg/mL aqueous dose of papH+Cl prepared at 35.0C. Kw at 35.0C is 2.1 1014.
