Titration and standardization 50mL buret is filled with 50mL of 1M NaOH solution (6.02g of NaOH in 150mL water). 1.55g of KHP is completely dissolved in water. Then titration of NaOH solution is done into KHP solution. 1) How do you standardize NaOH with KHP data? 2) How do you determine the volume of NaOH required to neutralize the KHP solution? 3) How do you determine the molarity of the sodium hydroxide solution?

Standardization of NaOH: Acid Base Titration Objective: In this lab, you will accurately determine the concentration of a solution of sodium hydroxide (NaOH) using a 0.500M potassium hydrogen phthalate (KHP) standard solution. Background: Acid–Base Titrations When an acid reacts with a base, a neutralization reaction occurs. The H+ ions from the acid and the HO– ions from the base combine to form water and are therefore neutralized. The other product of reaction is a salt. For example, hydrochloric acid reacts...

There will be a short quiz held at the beginning of the lab session. The quiz will be based on some of the material shown below. 1. A student performed a titration on a 5.00 mL sample of an unknown HCl solution, using 10.90 mL of 0.09345 M NaOH from a buret and phenolphthalein indicator. What was the concentration of the unknown HCI? Use the correct number of sign ificant figures. 2. Another student designed a procedure to determine the...
