Question

Substances dissolve through three processes: I. ionization II. dissociation III. dispersion Which lists the dissolving processes that change the identity of a substance?

Answer 1

The dissolving processes that change the identity of a substance in chemistry are ionization and dissociation.

Step-by-step explanation:

Dissolving Processes in Chemistry

The dissolving processes that change the identity of a substance are ionization and dissociation.

Ionization occurs when a substance forms ions in a solution. For example, when hydrochloric acid (HCl) dissolves in water, it ionizes into hydrogen ions (H+) and chloride ions (Cl-).

Dissociation happens when a compound breaks apart into its constituent ions in a solution. One example is table salt (NaCl) dissociating into sodium ions (Na+) and chloride ions (Cl-) when dissolved in water.

Dispersion is the process of solute particles spreading evenly throughout a solvent, without forming ions or breaking apart into ions. Dispersion does not change the identity of the substance.

Answer 2

I and II

Ionization and. Dissociation

Step-by-step explanation:

Dissociation,

Is to unbundle a compound into smaller, less complex constituents that are generally able to recombine under different conditions.

Ionization or ionisation,

Is the process in which an atom or a molecule accepts or loses electrons to become negatively or positively charged, it often is accompanied by with chemical changes.

Dispersion

The act of distributing things over a wide area.
