1.A buffer solution is prepared which consists of 0.100M HC2H3O2 and 0.100M NaC2H3O2, the dissociation constant, Ka of HC2H3O2 is 1.74 x 10^-5

Determine the pH after the addition of 10.0ml of 0.1M NaOH to 100.00ml of this buffer.

2. An aqueous solution of 100.0ml 0.100M NaCl is titrated with 0.100M AgNO3 (AgCl Ksp= 1.0x10^-10) pAg=-log[Ag+]

A. Calculate the pAg of the solution after 20.0ml of AgNO2 solution is added.

B. Calculate the pAg of the solution after 110.0ml of AgNO3 solution is added.
