Question

(Name?) (Name?)

Evidence a change occurred in the test tube: _____________

Balanced eqn: ___________________

Total ionic eqn: ___________________

Net ionic eqn: ___________________

More active metal: ___________ Element Oxidized: _______
Element Reduced: ___________________
Spectator ion: _____________

Answer 1

Evidence a change occurred in the test tube: What did you observe?

Balanced eqn: Pb(s) + Cu(NO3)2(aq) ==> Pb(NO3)2(aq) + Cu(s)

Total ionic eqn:
Pb + Cu^2+ + 2[NO3]^- ==> Pb^2+ + 2[NO3]^- + Cu

Net ionic eqn: Remove the spectator ion (the NO3^-). What's left is the net ionic equation.

More active metal: Pb replaced the Cu ion so Pb is the more active metal
Element Oxidized: Which metal (Pb or Cu^2+ lost electrons? The loss of electrons is oxidation.
Element Reduced: The metal not oxidized is the one reduced.
Spectator ion: see above.
