Redox Reactions & Net Ionic Equations Quiz

sc20.1+2 Balancing redox reactions

When writing an ion, use the carat (^) to designate charges. For example, hydrogen ion should be written as H^+, while sulfate ion should be written as SO4^2-.
When balancing redox reactions, you may select H+, OH- or H2O in the appropriate dropdown menu as necessary, or you may leave it blank. Don't forget coefficients!
