1.3 Oxidising and Reducing Agents Flashcards
What is an oxidation reaction
One where electrons are lost
What is a reduction reaction
One where electrons are gained
What is a redox reactions
When both oxidation and reduction occur
What is an oxidising agent
A substance that accepts electrons meaning it is reduced
What is a reducing agent
A substance which donates electrons meaning it is oxidised
What can electronegativity values be used to predict
Whether a substance is an oxidising or reducing agent
What type of agents are substances with high electronegativity values
Strong oxidising agents
What type of agents are substances with low electronegativity values
Strong reducing agents
