An HCI solution has a concentration of 0,09714 M. 25,00 mL of this solution was then diluted to 250.00 ml. in a volumetric flask. The diluted solution was then titrated against 10.00 mL of a saturated Ca(OH)z solution using methyl orange indicator to reach the endpoint.

a. What is the concentration of the diluted HCl solution?
b. If 6.82 mL of the diluted HCI solution was required to reach the endpoint, what is the concentration of OH in solution?
c. What is the concentration of Ca in solution?
d. What is the Kp expression for the dissolution of Ca(OH)2?
e. Calculate the value of the Kp for Ca(OH)2?
