Identify the Oxidizing agent and the reducing agent for Al(s)+3Ag^+(aq)--->Al^3+(aq)+3Ag(s)
Express your answers as chemical formulas serperated by a comma.
I tried putting in Al,3Ag^+
I keep getting it wrong and only have one attempt left I need help please.
Ag^+ is the oxidizing agent.
Al is the reducing agent.
So I would write Ag^+,Al
Remember, oxidation is the loss of electrons. Al goes from zero to +3 which is a loss of electrons; therefore, Al is oxidized which makes it the reducing agent.
Reduction is the gain of electrons. Ag^+ goes from +1 (each) to zero which is a gain of electrons. This is reduction so it is the oxidizing agent. You don't need the coefficients to identify the formula.
