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 2.65 grams of KHP are needed to exactly
neutralize 33.9 mL of a potassium
hydroxide solution, what is the concentration of the base
solution ?
Solution:
The neutralization of 1 mol of KHP requires 1 mol of KOH.
Therefore,
Number of moles of KOH required = Number of moles of KHP
Calculation:
Number of mol of KHP = mass / molar mass
= 2.65 g / 204.22 g mol-1 = 0.01298 mol
Thus, required number of moles of KOH = 0.01298 mol
Molarity = number of moles / Volume in L
Molarity = 0.01298 mol / 0.0339 L
Molarity = 0.383 M
