Question

calcium is an oxidizing agent or a reducing agent?

Answer 1

calcium is a reducing agent because it loses it electrons and oxidises itself and reduces it's other reactant

Answer 2

Calcium is a reducing agent.

Explanation:

• To identify whether calcium is an oxidizing agent or a reducing agent, the ionic charge of calcium must be found.
• Calcium belongs to the second group elements of the periodic table. All the elements present in group 2 have a +2 charge. Therefore the charge of calcium is $Ca^{2+}$.
• From the charge, it is evident that calcium involved in bonding by losing 2 electrons.
• As Ca is oxidized to $Ca^{2+}$, it acts as a reducing agent as it makes reduction to happen.
