mols KHP = grams/molar mass = ?
mols NaOH = mols KHP
M NaOH = mols NaOH/L NaOH
To standardize a solution of NaOH, one uses a primary standard called potassium hydrogen phthalate (KHP). It is a monoprotic acid. It has a molar mass of 204.33g/mol. Suppose you weigh out .556g of KHP and dissolve it in water. It requires 14.48 mL of NaOH to reach the endpoint. What is the concentration of the NaOH solution?
