A new weak acid, HG, has been synthesized. The a titration of 0.115g of HG requires 16.00 mL of 0.10 M KOH solution to reach the equivalence point.

(a) Write the dissociation equation for HG in water and its equilibrium expression (Ka).

(b) Write the net ionic equation for the titration reaction.

(c) Calculate the molar mass of HG.

(d) After 8.00 mL of the base is added, the pH of the solution is 6.20. What is the value for the Ka of HG?

(e) What is the value of Kb for the G- ion?

(f) What would be the effect on the pH if 500. mL of distilled water were added to the solution at the half-way point of the reaction? Justify.

(g) Calculate the pH of the solution at the equivalence point (assume total volume is 16.00 mL).
