An HCl solution has a concentration of 0.09714 M. Then 10.00 mL of this solution was then diluted to 250.00 mL in a volumetric flask. The diluted solution was then used to titrate 250.0 mL of a saturated AgOH solution using methyl orange indicator to reach the endpoint.

4. What is the K_sp expression for the dissolution of AgOH?

K_sp = [Ag⁺] + [OH]

K_sp = [Ag⁺] + [OH]²

K_sp = [Ag⁺][OH]²

K_sp = [Ag⁺][OH]
