Why is potassium hydrogen phthalate (KHP) used to standardize the NaOH solution instead of measuring out a known mass of solid NaOH to be dissolved in water? O KHP is an acid and will neutralize some of the NaOH to use later. O There is no reason, NaOH solutions can be used without standardization. O olid NaOH is hygroscopic and will absorb water, making it virtually impossible to determine a true initial mass and therefore changing the concentration of the solution. O Solid NaOH evaporates therefore its concentration can never be known.
