... A student carries out an experiment to standardize a sodium hydroxide solution. To do this, the student weighs out 1.3009 g sample of potassium hydrogen phthalate (KHC8H4O4 or KHP–molar mass 204.22 g/mol). The student dissolves the KHP in distilled water, adds phenolphthalein as an indicator, and ti ...
