A student is asked to standardize a solution of calcium hydroxide. He weighs out 0.934 g potassium hydrogen phthalate (KHC3H4O4, treat this as a monoprotic acid). It requires 32.5 mL of calcium hydroxide to reach the endpoint. A. What is the molarity of the calcium hydroxide |M solution? This calcium hydroxide solution is then used to titrate an unknown solution of hydroiodic acid. B. If 17.3 mL of the calcium hydroxide solution is required to neutralize 16.2 mL of hydroiodic acid, what i the molarity of the hydroiodic acid solution? M

Hi, I need help with both questions. Thank you!

**Standardizing a Solution of Calcium Hydroxide** A student is asked to standardize a solution of calcium hydroxide. The student weighs out 0.934 g of potassium hydrogen phthalate (KHC₈H₄O₄, treating it as a monoprotic acid). It requires 32.5 mL of calcium hydroxide to reach the endpoint of the titration. **A.** What is the molarity of the calcium hydroxide solution? - Molarity: [_____ ] M Once standardized, the calcium hydroxide solution is then used to titrate an unknown solution of hydroiodic acid. **B.** If 17.3 mL of the calcium hydroxide solution is required to neutralize 16.2 mL of hydroiodic acid, what is the molarity of the hydroiodic acid solution? - Molarity: [_____ ] M
