Neutralisation
A reaction between an acid and a base to produce a salt and water.
Strong acid
An acid that completely dissociates in water to produce a high concentration of H+ ions.
Strong base
A base that completely dissociates in water to produce a high concentration of OH- ions.
Neutral salt
A salt formed from the reaction of a strong acid and a strong base, resulting in a neutral pH solution.
Solid carbonates
Compounds that contain the carbonate ion (CO3) and react with acids to form salts, carbon dioxide, and water.
Full equation
The complete chemical equation showing the reaction between hydrochloric acid (HCl) and calcium carbonate (CaCO3) to produce calcium chloride (CaCl2), carbon dioxide (CO2), and water (H2O).
Ionic equation
The chemical equation representing the reaction between hydrochloric acid and calcium carbonate in terms of dissociated ions in solution, showing the formation of calcium ions (Ca2+), chloride ions (Cl-), carbon dioxide, and water.
