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 profe…
Question

Calculate the MW from the average EM. 

MW (g/mol) = n(eq/mol) x EM (g/eq)

where n is the number of H+ ions titrated per molecule of acid.

Information needed

There was two trials

1. EM = 113.26 g/eq

# equivalents of H+ = 0.00264

2. EM = 91.05 g/eq

# equivalents of H+ = 0.003295

The acid is Sulfamic Acid.
