What is a precipitate?
A
a change in color
B
a change in temperature
C
a solid formed
D
a gas formed
Explanation: 

Detailed explanation-1: -A precipitate is a solid formed in a chemical reaction that is different from either of the reactants. This can occur when solutions containing ionic compounds are mixed and an insoluble product is formed. The identity of the precipitate can often be determined by examining solubility rules.

Detailed explanation-2: -Precipitation is the formation of a solid in a solution during a chemical reaction. When the reaction occurs, the solid formed is called the precipitate, and the liquid remaining above the solid is called the supernate.

Detailed explanation-3: -A precipitate is a solid formed when the cation and anion in an aqueous solution react to form an insoluble compound. An ionic solution is when the ions of a compound have dissociated in an aqueous solution.

Detailed explanation-4: -Precipitation Example Mixing silver nitrate and sodium chloride in water will cause silver chloride to precipitate out of solution as a solid. In this example, the precipitate is silver chloride.
