The ionic metals are converted to an insoluble form (particle) by the chemical reaction between the soluble metal compounds and the precipitating reagent. In most methods the precipitate is the product of a simple metathesis reaction between the analyte and the precipitant; however, any reaction generating a precipitate can potentially serve as a gravimetric method. Most precipitation gravimetric methods were developed in the nineteenth century, or earlier, often for the analysis of ores. Precipitation refers to a chemical reaction that occurs in aqueous solution when two ions bond together to form an insoluble salt, which is known as the precipitate.

That process is defined as precipitating. Precipitates can be coloured or not. Forming precipitates and colours of precipitates are used to identify anions, cations, and compounds. e.g: CaCO 3 (solid phase) does not dissolved in water (liquid Precipitation is the process of conversion of a chemical substance into a solid from a solution by converting the substance into an insoluble form or a super-saturated solution. [1] [2] When the reaction occurs in a liquid solution, the solid formed is called the precipitate .

Allow the precipitate to settle, decant the supernatant solution, and repeat this twice to completely rinse the precipitate. Filter the precipitated mercury(I) chloride with a sintered glass crucible, rinsing quickly with four portions of cold distilled water, and then transfer it to a vacuum desiccator.
