EX CHE 212 11. Determine the pH a 1.00 L buffer solution is 0.250 M in HF (K, -3.5 x 10) and 0.250 M in NaF solution after the addition of 100.0 mL of 1.00 M HCL.

A buffer solution that is 0.397 M in HCN and 0.397 M in KCN has a pH of 9.40. The addition of 0.01 mol of H3 O* to 1.0 L of this buffer would cause the pH to The capacity of this buffer for added OH could be increased by the addition of 0.137 mol

K; for the complex ion Ag(NH,),* is 1.7 x 10. K, for AgCl is 1.6 x 10-10. Calculate the molar solubility of ARCI in 1.0 M NH3.

A buffer solution contains 0.316 M KHCO3 and 0.357 M K₂CO3. If 0.0170 moles of sodium hydroxide are added to 125 mL of this buffer, what is the pH of the resulting solution? (Assume that the volume does not change upon adding sodium hydroxide) pH =
