Use a primary standard to determine an unknown concentration using an acidâbase titration. Close Problem Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP. If 3.442Ã101 mL of a sodium hydroxide solution are needed to neutralize 1.761Ã100 grams of KHP, what is the concentration (mol/L) of the sodium hydroxide solution?
