(if you are talking about aqueous ionic compounds) when you mix 2 solutions containing ions from ionic compounds a solid is sometimes formed, which is called a precipitate
During a chemical reaction, a precipitate is sometimes formed in the solution. The precipitation is the solid that is formed within a solution.
A solution is formed as individual molecules from the solid are surrounded by molecules of solvent and then diffusing away from the surface of the solid being dissolved.
If a solution is formed after the water evaporation the initial solid is obtained.
A solution
Crystal
A solid solution is formed when two crystalline solids combine to form a crystal lattice. One example of a solid solution is copper and zinc mixing to create brass.
What is left is a solution.
A "precipitate".
One way to tell that a solid has formed a solution with water is if the solid has completely dissolved in the water, resulting in a clear and homogeneous mixture. You can observe this by checking if there are no visible solid particles remaining in the water.
When a solid falls out of solution, it is called a precipitate. A precipitate is formed when a chemical reaction occurs in a solution and the product that is made is insoluble.
A solid solution is formed when two crystalline solids combine to form a crystal lattice. One example of a solid solution is copper and zinc mixing to create brass.
In this case a solution is formed.
