<h3>What is Gravimetric analysis?</h3>
This is a method which is used in the determination of the quantitative determination of the ion being analyzed(analyte) based on its mass.
Adding an excess amount of precipitating ions to a solution containing an analyte will make it easier for the mass of an analyte to be determined.
