1. A solution of sodium hydroxide (NaOH) was standardized against potassium hydrogen phthalate (KHP). A known mass of KHP was titrated with the NaOH solution until a light pink color appeared using phenolpthalein indicator. Using the volume of NaOH required to neutralize KHP and the number of moles of KHP titrated, the concentration of the NaOH solution was calculated. Molecular formula of Potassium hydrogen phthalate: HKC8H404 Mass of KHP used for standardization (g) 0.5100 Volume of NaOH required to neutralize...

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...

When 4.15g of potassium hydrogen phthalate (KHPh M=204.2 g/mol) is titrated with KOH solution and it takes 46.42 mL of the base to reach the endpoint, calculate the concentration (M) of the KOH solution. I'm confused about the wording of the problem and how to approach it. Does titrated mean just a normal chemical equation problem like KHP + KOH -> ???, or am I suppose to do something special? Also, what does it mean to reach the endpoint? Or...
