Avoid temperatures much higher than this because the acid may decompose. Once the samples have been dried, store them in your desiccator. A point of note, standardization of NaOH and its subsequent use as a titrant are best done

Web27 mrt. 2024 · KH P being "monoprotic" means that one mole of KH P is one equivalent. Basically, 1 molecule of KH P only donates 1 H + ion. We also know that N aOH is a monoprotic base, because there's only one OH − ion in its chemical formula. Therefore, 1 mole of KH P will correspond to 1 mole of N aOH in a neutralisation reaction.
