Steps in a Gravimetric Analysis

1 Steps in a Gravimetric AnalysisAfter appropriate dissolution of the sample, the following Steps should be followed for a successful Gravimetric procedure:1. Preparation of the Solution: This may involve several Steps including adjustment of the pH of the solution in order for the precipitate to occur quantitatively and get a precipitate of desired properties, removing interferences, adjusting the volume of the sample to suit the amount of precipitating agent to be Precipitation:This requires addition of a precipitating agent solution to the sample solution. Upon addition of the first drops of the precipitating agent, supersaturation occurs, and then nucleation starts to occur where every few molecules of precipitate aggregate together forming a nucleous.
