A chemistry student needs to standardize a fresh solution of sodium hydroxide. He carefully weighs out 360. mg of oxalic acid (H,C,0,), a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250. mL of distilled water. The student then titrates the oxalic acid solution with his sodium hydroxide solution. When the titration reaches the equivalence point, the student finds he has used 97.4 mL of sodium hydroxide solution. Calculate the molarity student's sodium hydroxide solution. Round your answer to 3 significant digits. of the

Precipitation Titration

Precipitation analysis is used to analyze drugs, and to measure the salt content in food and beverages. It is an important concept from the examination point of view many practical questions are asked on the topic. This topic is significant in the professional exams for both undergraduate and graduate courses, especially for
