molar mass of KHP = 204.22 gm/mol then 2.12 gm of KHP = 2.12 / 204.22 = 0.010381 mole
Neutrilization reaction between KHP and NaOH take place in equimolar proportion thus to react with 0.010381 mole of KHP required NaOH = 0.010381 mole
23.12 ml = 0.02312 L
Molarity = no. of mole / volume of solution in liter
Molarity of NaOH = 0.010381 / 0.02312 = 0.449 M
Concentration of NaOH soution = 0.449 M

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...

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...
