CHEMICAL EFFECTS OF ELECTRIC CURRENT
Liquids can conduct electricity, but not all liquids do so. The ability of a liquid to conduct electricity depends on the presence of ions in the liquid. Pure water, for example, does not conduct electricity well because it lacks free ions. However, many other liquids, such as saltwater or acids, can conduct electricity due to the presence of dissolved ions.
Liquids that contain ions, such as saltwater, acids, and bases, can conduct electricity. The ions in these liquids are free to move, which allows them to carry electric charge through the liquid.
1.Saltwater: When salt (sodium chloride) dissolves in water, it dissociates into sodium (Na⁺) and chloride (Cl⁻) ions. These ions can move freely in the solution, allowing it to conduct electricity.
2.Acids and Bases: Acids, such as hydrochloric acid (HCl), dissociate into hydrogen (H⁺) and chloride (Cl⁻) ions in water. Similarly, bases like sodium hydroxide (NaOH) dissociate into sodium (Na⁺) and hydroxide (OH⁻) ions. The presence of these ions allows the solutions to conduct electricity.
