M A student is asked to standardize a solution of potassium hydroxide. He weighs out 1.01 g potassium hydrogen phthalate (KHCH.04. treat this as a monoprotic acid). It requires 20.4 mL of potassium hydroxide to reach the endpoint A. What is the molarity of the potassium hydroxide solution" This potassium hydroxide solution is then used to tatrate an unknown solution of hydrolodic acid B. If 13.1 ml. of the potassium hydroxide solution is required to neutralize 14,5 ml of hydrolodic acid, what is the molarity of the hydrolodic acid solution? M M M A student is asked to standardize a solution of barium hydroxide. He weighs out 1.01 g potassium hydrogen phthalate (KHC,HO, treat this as a monoprotic acid) It requires 35.3 mL of barium hydroxide to reach the endpoint A. What is the molarity of the barium bydroxide solution? This barium hydroxide solution is then used to tittate an unknown solution of nitric acid B. If 29.5 ml of the barium hydroxide solution is required to neutralize 12.3 ml of nitric acid, what is the molarity of the nitric acid solution? M Sited A student is asked to standardize a solution of calcium hydroxide. He weighs out 1.01 g potassium hydrogen phthalate (KHCHO treat this as a monoprotic acid) It requires 30.4 ml of calcium hydroxide to reach the endpoint A. What is the molarity of the calcium hydroxide solution? M This calcium hydroxide solution is then used to tittate an unknown solution of hydrobromic acid B. If 24.0 mL of the calcium hydroxide solution is required to neutralize 19.7 ml. of hydrobromic acid, what is the molarity of the hydrobromic acid solution? M
