As during titration, the NaOH solution in the buret will be exposed to air, the buret used was prepared for use only when it was needed, and fresh sodium hydroxide should be added if it. After the titration has reached the endpoint, a final volume is read from the buret. The hydrogen atoms bonded to the oxygen atoms at the ends of the tartaric acid What are the units used for the ideal gas law? Potassium hydrogen L-tartrate is used for stabilizing egg whites, whipped cream and for anti-caking and thickening. At the equivalence point, the stoichiometric ratio will apply, and we can use it to calculate the amount of KMnO4 which must be added: \[n_{\text{KMnO}_{\text{4}}}\text{(added)}=n_{\text{H}_{\text{2}}\text{O}_{\text{2}}}\text{(in flask)}\times \text{S}\left( \dfrac{\text{KMnO}_{\text{4}}}{\text{H}_{\text{2}}\text{O}_{\text{2}}} \right) \nonumber \].
