answer:When a metal hydroxide MOH dissociates in water, it releases metal ions (M+) and hydroxide ions (OH-). The dissociation reaction can be represented as follows: MOH (s) → M+ (aq) + OH- (aq) For example, when sodium hydroxide (NaOH) is dissolved in water, it dissociates to produce sodium ions (Na+) and hydroxide ions (OH-): NaOH (s) → Na+ (aq) + OH- (aq) The dissociation of other metal hydroxides, such as calcium hydroxide (Ca(OH)2) or magnesium hydroxide (Mg(OH)2), follows a similar pattern, where the metal hydroxide produces metal ions and hydroxide ions upon dissolving in water.

answer:When a metal hydroxide MOH dissociates in water, it produces hydroxide ions (OH-) which makes the solution basic. Therefore, MOH dissociation results in a basic solution.

answer:NaF, or sodium fluoride, is a salt formed from a strong base (NaOH) and a weak acid (HF). It hydrolyzes in water to produce a basic solution due to the presence of residual hydroxide ions from the incomplete reaction of fluoride ions with water molecules. Therefore, NaF is a basic salt.

answer:LiOH is a strong base, so it is basic. KBr is a salt of a strong acid (HBr) and a strong base (KOH), so it is neutral. HI is a strong acid, so it is acidic. NaF is a salt of a strong base (NaOH) and a weak acid (HF), so it is basic.
