1. Potassium hydrogen phthalate is a solid,monoprotic acid frequently used in the laboratory to standardizestrong base solutions. It has the unwieldy formula ofKHC8H4O4. This isoften written in shorthand notation as KHP.
How many grams of KHP are needed to exactly neutralize23.2 mL of a 0.557 Mpotassium hydroxide solution ?
2. Potassium hydrogen phthalate is a solid,monoprotic acid frequently used in the laboratory to standardizestrong base solutions. It has the unwieldy formula ofKHC8H4O4. This isoften written in shorthand notation as KHP.
What volume of a 0.458 M potassiumhydroxide solution is needed to exactly neutralize2.67 grams of KHP ?
3. A student is asked to standardize a solution ofbarium hydroxide. He weighs out1.04 g potassium hydrogen phthalate(KHC8H4O4, treat this as amonoprotic acid).
It requires 37.9 mL of bariumhydroxide to reach the endpoint.
A. What is the molarity of the bariumhydroxide solution?
This barium hydroxide solution is then used totitrate an unknown solution of hydrobromicacid.
B. If 21.7 mL of thebarium hydroxide solution is required toneutralize 13.0 mL of hydrobromicacid, what is the molarity of the hydrobromicacid solution?
4. A student is asked to standardize a solution ofcalcium hydroxide. He weighs out1.04 g potassium hydrogen phthalate(KHC8H4O4, treat this as amonoprotic acid).
It requires 32.9 mL of calciumhydroxide to reach the endpoint.
A. What is the molarity of the calciumhydroxide solution?  M
This calcium hydroxide solution is then used totitrate an unknown solution of hydroiodicacid.
B. If 16.2 mL of thecalcium hydroxide solution is required toneutralize 20.4 mL of hydroiodicacid, what is the molarity of the hydroiodicacid solution?  M
