Some substances dissolve when you mix them with water. When a substance dissolves, it looks like it disappears. But in fact it has just mixed with the water to make a transparent (see-through) liquid called a solution. When you mix sugar with water, the sugar dissolves to make a transparent solution. Salt dissolves in water too. Heat can help some substances dissolve faster in water. Salt, for example, will dissolve quicker in hot water than in cold water.

What is a solid formed from liquid reactants during a chemical reaction? It is called a precipitate. in solution may react to form other compounds whose solubility in the liquid medium is less than that of the original compounds. When this occurs the new compound drops out of the solution as a solid. An example would be the reaction of silver nitrate and sodium chloride in water. The resulting silver chloride will precipitate out of the solution as a solid. Show more >
