Oxidising and reduction- Chemistry?
Oxidation and reduction can be described as the loss and/or gain of electrons from an ion or atom (species) in a chemical reaction. For the following aqueous reaction, select the species that is oxidized and similarly the one that is reduced:
Al(s) + 3Ag^+(aq) = 3Ag(s) + Al^3+(aq)
Which is the reactant species that is oxidising and which is the reactant species that is reducing?

You need to know the oxidation states and determine which ones change.
Al is zero on the left and +3 on the right; therefore, Al has lost electrons.
Ag is +1 on the left and zero on the right; therefore Ag has gained electrons. Al is oxidized; Ag is reduced.

you mean Al^3+ is oxidized ,Ag^+ is reduced.
