Common precipitation reactions
WebPrecipitation is one type of chemical reaction which involves the formation of one or more insoluble products. Precipitation reactions, also called double displacement reactions can be summarized with the following reaction equation: AB(aq)+CD(aq) AD(s)+ CB(aq)or(s) AB ( a q) + CD ( a q) AD ( s) + CB ( a q) o r ( s) WebJul 1, 2014 · Precipitation, or double-replacement reaction A reaction that occurs when aqueous solutions of anions (negatively charged ions) and cations (positively charged ions) combine to form a compound that is insoluble is known as precipitation. The insoluble solid is called the precipitate, and the remaining liquid is called the supernate. See Figure2.1
