Ionic Equations

Equations ____________ – show the complete chemical formulas. Does not indicate ionic character ____________– shows all ions. Actually how the particles exist in the solution

Steps for Writing Ionic Equations Write the balances molecular equation (balanced chemical equation) Break every thing down into its ions EXCEPT the solid, gas, or water (complete ionic equation) Cross out everything that is the same on both sides (spectator ions) Write what is left (net ionic equation)

Rules When writing ionic equations, you must keep together the solid, gas, or water ____________– ions that appear on both sides of the equation. They have very little to do with the chemical reaction

Example Write the balanced chemical equation, the complete ionic equation, and the net ionic equation for: lead (II) nitrate and potassium iodide. Solid potassium iodide will be formed.

Another Example Write the balanced chemical equation, complete ionic equation, and net ionic equation for: calcium chloride and sodium carbonate. Solid calcium carbonate will be formed.

What if water is formed? Write the balanced chemical equation, complete ionic equation, and net ionic equation for: Calcium hydroxide and nitric acid
