Question

Check your ability to correctly define some of the terms associated with redox reactions.

(a) A chemical species that gets reduced during a chemical reaction: loses electrons or gains electrons?

(b) A chemical species that gets reduced during a chemical reaction: changes to a more negative oxidation state or changes to a more positive oxidation state?

(c) A chemical species that gets reduced during a chemical reaction: is a reducing agent or is an oxidizing agent?

(d) A chemical species that gets reduced during a chemical reaction: has a high-energy filled orbital or has a low-energy unfilled orbital?

(e) A chemical species that gets reduced during a chemical reaction: obtains electrons from a reducing agent or obtains electrons from an oxidizing agent?

Explanation / Answer

(a) A chemical species that gets reduced during a chemical reaction: loses electrons or gains electrons?

Ans: The reduced species gains electron
