When two aqueous solutions are combined the reaction forms a solid that settles solution. What is this solid called?
The solid that forms when two aqueous solutions are combined is called a precipitate .
The following video shows the addition of an aqueous, clear, and colorless lead(II) nitrate solution to an aqueous, clear, and colorless potassium iodide solution. The precipitate is a yellow solid called lead(II) iodide, which is insoluble in water.
