Anion (negative ion)Īlkali metal ions (Li +, Na +, K +, etc.)Īs with most problems, this breaks down into several simpler ones. To make this determination, it helps to know the solubility rules- which all students of chemistry were at one time required to memorize, but are nowadays usually obtained from tables such as the one shown below. ![]() The formation of a precipitate is often indicated by underscoring.įrom the above example involving silver chloride, it is clear that a meaningful net ionic equation can be written only if two ions combine to form an insoluble compound. When a solid is formed in a reaction that takes place in solution, it is known as a precipitate. ![]()
