Likewise, what does a precipitate look like? In chemistry, a precipitate is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid from solution is called precipitation. Often the precipitate emerges as a suspension. Precipitates can also form when the temperature of a solution is lowered.

Simply so, what is the Colour of Agcl precipitate?


Is precipitation a physical change?
