A student weighs a sample of potassium hydrogen phthalate (KHP) to prepare a primary standard for a titration. She later discovers that the KHP was contaminated with sugar. To determine the amount of KHP in the mixture, she takes 5.942 g of the mixture and make a 100.0 mL solution. The student then titrates 10.00 mL of this solution with a 0.1491 M sodium hydroxide solution. She finds that 13.12 mL of the NaOH solution is needed to reach the...

A solution of NaOH has an unknown concentration. When 1.396 g of potassium hydrogen phthalate (KHP a monoprotic acid frequently used as an analytical standard) is titrated with the sodium hydroxide the end point is 42.54 mL. Use this information to compute the concentration of NaOH in the solution. The molar mass of KHP is 204.22 g mol1. [OH mol L
