BUFFERS, HYDROLYSIS OF SALTS
BUFFERS, HYDROLYSIS OF SALTS (16 PTS) 1. A 0.0450 M Ca(X)2 has a pH of 11.079. Ca(X)2 is composed of a Ca²+ cation and an unknown anion X, which undergoes hydrolysis. A. Write the balanced dissociation reaction of Ca(X)₂ into its ions. Write your answer on your solution sheet B. Write the balanced hydrolysis reaction of the unknown anion, X. Write your answer on your solution sheet C. Calculate the K₁ or K₂ of X. D. Given the following Ką values of different weak acids, determine the identity of X. Weak acids Ka HIO 2.00 x 10-11 6.17 x 10-10 1.80 x 10-5 4.00 x 10-4 HCN CH3COOH HNO₂
