Assertion : In the reaction `Zn(s)+Cu^(2+)(aq)rarrZn^(2+)(aq)+Cu(s)Cu^(2+)` ions acts as oxidising agent and Zn atoms act as a reducing agent
Reason : A substance (atom, ion, or molecule) which readily gain electrons from other substances is an oxidising agent while reducing agent is a substance (atom, ion or molecule) which can lose electrons to other substances.
