Here's the equation for the strong electrolyte strontium nitrate dissolving in water:
`Sr(NO_3)_2_(s) -> Sr^(2+) _(aq) + 2NO_3^(-)_(aq)`
This says that a molecule of solid strontium nitrate produces one aqueous strontium ion and two aqueous nitrate ions. Water isn't included in the equation because it doesn't ionize, so it's liquid water both on the reactant and the product side of the equation. The subscript (aq) means aqueous and indicates that the ions are associated with water molecules.
A substance that is a strong electrolyte has high solubility in water, so it ionizes completely. Electrolytes are substances that conduct electricity when dissolved in water. The ions act as carriers of charge so that electrical charges can move through the solution in response to an electrical potential difference. Electrolytes can be soluble salts like strontium nitrate or acids or bases.
