WebThe principle of gravimetric analysis is based on the estimation of the mass percent of an ion in an impure compound of known quantity by determining the mass of the same ion in a pure compound. In order to determine the mass, the ion of interest needs to be completely isolated. This isolation of ions is done with the help of precipitation. pothole season
