Web1 apr. 2024 · KHP stands for potassium hydrogen phthalate, which has the chemical formula KHC8H4O4. When KHP and NaOH combine, a positive hydrogen ion leaves the KHC8H4O4 and a negative hydrogen atom leaves the NaOH. These two atoms combine with the oxygen from the NaOH to form H2O, which is the chemical formula for water. WebYou can calculate normality using any of the following formulae: Normality (N) = (Mass of the solute) / (Equivalent mass of the solute (E) × Volume of the solution (V) ) Normality (N) = W g / E g × V = Equivalent weight per liter / ( W × V ) Note that in the above formulae the volume of the solution V should be in in liters.
