Chemistry Reactions and Definitions

These flashcards cover key terms and concepts related to various types of chemical reactions, their definitions, and characteristics.

Combustion reaction

Involves oxygen reacting with a fuel to produce heat and oxidized products.

Acid-base reaction

Involves the transfer of H+ ions between reactants.

Precipitation reaction

Forms a solid from two solutions mixing, resulting in an insoluble substance.

Gas evolution reaction

Releases gas from a reaction, producing substances such as CO₂ or H₂.

Spectator ions

Ions that do not participate in the actual chemical reaction.

Neutralization reaction

Occurs between acids and bases, forming water and salt.

Oxidation-reduction (redox) reaction

Involves the transfer of electrons, where one species is oxidized (loses electrons) and another is reduced (gains electrons).

Strong electrolytes

Compounds that exhibit good conductivity in solution.

Cation

A positively charged ion, often associated with metals.

Salt

A compound formed from the reaction of an acid and a base.
