WebQ > K sp: the reaction proceeds in the reverse direction (solution is supersaturated; precipitation will occur) In solutions containing two or more ions that may form insoluble compounds with the same counter ion, an experimental strategy called selective precipitation may be used to remove individual ions from the solution. WebPrecipitation gravimetry is a quantitative analytic technique that can be used to determine the mass of an analyte. The analyte can be removed from the solution by forming a precipitate with a known composition. By weighing the precipitate and working backward, the initial mass of the analyte present in the solution can be determined. reclaim working from home allowance

WebIn qualitative analysis, the identity, not the amount, of metal ions present in a mixture is determined. The technique consists of selectively precipitating only a few kinds of metal ions at a time under given sets of conditions. Consecutive precipitation steps become progressively less selective until almost all the metal ions are precipitated.
