Is khp hygroscopic
Witryna15 sty 2024 · Solid NaOH is highly hygroscopic (it absorbs water from the air) and thus it cannot be accurately weighed. A KHP sample of known mass (and, therefore, known moles) can be titrated with the NaOH solution to determine very precisely the concentration of the NaOH. This procedure is called standardizing the NaOH solution. Witryna30 gru 2013 · Potassium hydrogen phthalate, KHC8H4O4 (abbreviated KHP), is a non-hygroscopic, crystalline, solid that behaves as a monoprotic acid.
