Chemical precipitation is a process where dissolved substances in a solution form solid particles, known as precipitates. This occurs when the concentration of certain ions exceeds their solubility limit, often due to changes in temperature, pH, or the addition of other chemicals. Precipitation is commonly used in various fields, including water treatment and analytical chemistry. During precipitation, the solid particles can be separated from the liquid through filtration or sedimentation. This technique is essential for removing impurities from solutions or recovering valuable materials. Examples of precipitates include calcium carbonate and silver chloride, which can form in specific chemical reactions.
