Introduction

It is often crucial to test a solution of unwell-known concentration with a solution of a known, precise concentration. The procedure of determining the unknown’s concentration is referred to as standardization.

You are watching: Why does naoh need to be standardized

Solutions of sodium hydroxide are practically difficult to prepare to a precise molar concentration because the substance is hygroscopic. In fact, solid NaOH absorbs so a lot moisture from the air that a measured sample of the compound is never before 100% NaOH. On the other hand also, the acid salt potassium hydrogen phthalate, KHC8H4O4, have the right to be measured out in specific mass quantities. It reacts through NaOH in a basic 1:1 stoichiometric ratio, thus making it a suitable substance to usage to standardize a solution of NaOH.

Objectives


In this experiment, you will

Prepare an aqueous solution of sodium hydroxide to a target molar concentration.Determine the concentration of your NaOH solution by titrating it through a solution of potassium hydrogen phthalate, abbreviated KHP, through an accurate molar concentration.
