* Decomposition: This is the general term for a compound breaking down into simpler substances. It can be caused by heat, light, electricity, or chemical reactions.
* Dissociation: This refers to the breaking apart of a compound into its ions in a solution. For example, salt (NaCl) dissociates into sodium ions (Na+) and chloride ions (Cl-) in water.
* Hydrolysis: This is a specific type of decomposition where water is involved in breaking apart a compound. For example, the hydrolysis of sucrose (table sugar) breaks it down into glucose and fructose.
* Cleavage: This term is usually used in organic chemistry and refers to the breaking of a covalent bond in a molecule.
So, the best term to use depends on the specific context and the mechanism of the breakdown.
