Redox Reactions Quiz

Oxidation and reduction occur simultaneously in redox reactions. Where there is oxidation, there is always reduction.

Oxidation is the loss of electrons, reduction is the gain of electrons, oxidant (oxidising agent) is the species that causes another to be oxidized, and reductant (reducing agent) is the species that causes another to be reduced.

The concept of oxidation number can be used to identify oxidants and reductants by determining the change in oxidation number of each element in the reaction.

<p>Redox reactions can be classified into combination (synthesis), decomposition, displacement, and disproportionation reactions. Combination reactions involve the synthesis of a compound, decomposition reactions involve the breakdown of a compound, displacement reactions involve the displacement of one element by another, and disproportionation reactions involve the same element being simultaneously oxidized and reduced.</p> Signup and view all the answers

<p>Chemical equations in redox reactions can be balanced using the half-reaction method by balancing the number of electrons transferred in each half-reaction and then combining the half-reactions to ensure conservation of mass and charge.</p> Signup and view all the answers
