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

What is the concentration of a sodium hydroxide solution if 0.2033 g of potassium hydrogen phthalate (KHP- MW 204.22 g/mol) requires 10.40 mL of NaOH solution to reach the phenolphthalein end point? Answer with three decimal places.
Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory to standardize strong base solutions. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP. If 2.20 grams of KHP are needed to exactly neutralize 31.2 mL of a potassium hydroxide solution, what is the concentration of the base solution ? ANSWER: is in M potassium hydroxide
4) Potassium hydrogen phthalate (KHP) is the primary standard for evaluating the concentration of potassium hydroxide (KOH) solutions in terms of moles per Liter. In the course of a typical titration, one mole of KHP neutralizes one mole of KOH. 1.000 grams of KHP (molar mass = 204.2 grams per mole) consumed 43.3 mL of a given KOH (potassium hydroxide) solution. What is the molarity of the KOH solution? (5 points)
