EVERYDAY SCIENCE

Detailed explanation-1: -The ions or molecules in two solutions can react to form a solid. A solid formed from two solutions is called a precipitate.

Detailed explanation-2: -Tell students that sometimes when two liquids are mixed, a solid forms. This solid is a new substance, and it’s called a precipitate.

Detailed explanation-3: -Precipitation is the process of formation of an insoluble solid when solutions are mixed. The solid thus formed is called precipitate.

Detailed explanation-4: -Carmoisine and Erythrosine are the chemical used to imaprt red colour to the food substances.

Detailed explanation-5: -We can use the reaction quotient to predict whether a precipitate will form when two solutions containing dissolved ionic compounds are mixed. If Q < Kₛₚ, the newly mixed solution is undersaturated and no precipitate will form. If Q > Kₛₚ, the solution is oversaturated and a precipitate will form until Q = Kₛₚ.
