Definitions:

Electrolyte

A chemical compound capable of conducting electric current by being broken down into ions. Electrolytes can be acids or alkalis.

Acid

A substance that releases hydrogen ions when dissolved in water, typically having a pH less than 7 and capable of turning blue litmus paper red.

Alkali

A base that dissolves in water, typically found among the group 1 elements of the periodic table, such as sodium and potassium, which form strongly basic hydroxides.

Ion

A charged atom.
