QuestionChemistry
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?

\text{Oxidizing Agent} + \text{Reducing Agent} \rightarrow \text{Reduced Products}
A chemical species that gets reduced during a chemical reaction: - Gains electrons - Changes to a more negative oxidation state - Is an oxidizing agent - Has a low-energy unfilled orbital - Obtains electrons from a reducing agent Let me break down each part: (a) A chemical species that gets reduced GAINS electrons (b) A chemical species that gets reduced changes to a MORE NEGATIVE oxidation state Note the reduction in oxidation state from + 3 to + 2 (c) A chemical species that gets reduced IS AN OXIDIZING AGENT - Oxidizing agents cause reduction - They themselves get reduced in the process (d) A chemical species that gets reduced has a LOW-ENERGY UNFILLED orbital (e) A chemical species that gets reduced OBTAINS ELECTRONS FROM A REDUCING AGENT
Final Answer
(a) Gains electrons (b) Changes to a more negative oxidation state (c) Is an oxidizing agent (d) Has a low-energy unfilled orbital (e) Obtains electrons from a reducing agent
