![]() A substance that produces ions upon dissolution in water is termed an electrolyte. ![]() Certain substances dissociate to produce ions when they are dissolved in water. To understand the chemical change that takes place in such a reaction, it is important to understand how the substances that are dissolved in water actually exist in the solution. Since one of the products of the exchange is insoluble, and comes out of solution as a solid precipitate, this type of metathesis reaction is also classified as a precipitation reaction. K, which starts paired up with I, ends up paired with the other anion, NO3. Pb2, which starts paired up with NO, ends up paired with the other anion, 1. The cations in the reactant compounds "switch partners" so that they end up paired with a different anion on the product side of the reaction. For example, when an aqueous solution of lead (II) nitrate (Ph[NO3)2) is mixed with an aqueous solution of potassium iodide [KI), the following reaction occurs: Pb(NO3)2(aq) + 2 Kl(aq) → Pblz(s) + 2 KNO3(aq) (1) Equation (1) is an example of a methathesis. the substances involved in the reaction are dissolved in water.
