Oxidation Reduction Reactions?

Question

For the equation Ag + NO3 - -> Ag + + NO

What substance is reduced?
What substance is oxidized?
What is the half reaction for oxidation?
What is the half reaction for reduction?
What is the net balanced equation?
What is the reduced equation?

Answer 1

Silver is being oxidized, nitrogen from the nitrate is being reduced.

Oxidation half reaction:
Ag --> Ag+ + e

Reduction half reaction:
NO3- + 4H+ + 3e --> NO + 2H2O

Net balanced and reduced equation:
3Ag + NO3- + 4H+ --> 3Ag+ + NO + 2H2O

Answer 2

Remember OIL RIG:

Oxidation
Is
Loss

Reduction
Is
Gain

Loss of electrons, gain of electrons

Redox rections

Answer 3

One good trick that I remember from my undergrad was "LEO" (Lose electrons oxidation) and "GER" (gain electrons reduction) ... the species being oxidized is the on that is losing election (i.e. becoming more positive or less negative) and conversely, the species being reduced is the one that is gaining electrons, or becoming more negative (less positive)

Answer 4

Do people just write their homework questions into Yahoo answers without even trying for one second to answer them? Unbelievable....how about taking 1 minute to look it up in your standard textbook instead of taking three minutes to get somebody else to write it up on yahoo. PATHETIC.
