The net ionic equation for the reaction involved:
KHP(aq) + OH-(aq) → KP-(aq) + H2O(l)
The amount of KHP is the basis of the amount of NaOH consumed in the above reaction.
Suppose your laboratory instructor inadvertently gave you a sample of KHP contaminated with NaCl to standardize your NaOH. How would this affect the molarity you calculated for your NaOH solution? Justify your answer.
