In an acid base titration lab, a student determined that a NaOH solution was 0.1885 M. The student then used this NaOH solution to titrate with an unknown H2SO4solution. 25.00 mL of the unknown H2SO4solution was pipetted into an Erlenmeyer flask. This acid required 32.55 mL of the NaOH titrant to reach the endpoint. What is the molarity of the H2SO4?H2SO4+ 2 NaOH →Na2SO4+ 2 HOH

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
