Is khp acidic
WitrynaPotassium hydrogen phthalate, often called simply KHP, is an acidic salt compound. It forms white powder, colorless crystals, a colorless solution, and an ionic solid that is the monopotassium salt of phthalic acid. KHP is slightly acidic, and it is often used as a … Witryna11 lip 2024 · Ok,KHP is a monoprotic acid. In a titration where neutralization occurs, it is 1 H + to 1 OH-molar ratio.If we can figure out how many moles of KHP there is, we would find how many moles of H + there is (KHP to H + is a 1 to 1 molar ratio-monoprotic acid thing again).This can be found by dividing the molar mass of KHP into the mass of …
