Document Summary

Explain what makes khp a good primary standard. It is a solid acid, so weight can be measured accurately. Explain the titration process using khp and naoh, include the reaction and how it difers from a typical reaction in terms of the controlled addition of naoh. The khp is titrated with naoh through a buret. Khp and naoh reactions are 1-to-1 ratios, meaning the number of moles of naoh equal the number of moles of khp at equivalence point. In this particular reaction, the endpoint is very close to equivalence point. Endpoint is when the indicator in a reaction turns color to say that the reaction has reached conclusion, possible because of an indicator. Equivalence is the point where moles of base are equal to moles of acid. Describe two sources of error in the titration experiment to standardize a naoh solution and explain how the errors would afect your calculated value of molarity.
