Half-Reaction EquationsWorksheet 2

Date: Name: Class:

Ionic, net ionic and half-reaction equations.

Examine the following situations. If appropriate, write balanced ionic and net ionic equations to describe the situations. If the situations are redox reactions, write oxidation and reduction half-reaction equations. Refer to the activity series for metals and solubility guidelines if necessary.

1. A solution of lead(II) nitrate is mixed with a solution of potassium iodide. (4 marks)
