Question
Choose the correct reaction from the following regarding Arrhenius acid and base:-
- KOH (aq) → K+ (aq) + OH- (aq)
- H2SO4 (aq) → 2 H+ (aq) + SO42- (aq)
- HCl (aq) → OH- (aq) + Cl- (aq)
- Mg(OH)2 (aq) → Mg2+ (aq) + 2 OH- (aq)
The correct answer is: HCl (aq) → OH- (aq) + Cl- (aq)
According to Arrhenius theory, bases are substances (or species) that generate hydroxyl ions OH- (aq).
According to Arrhenius theory, acids are the substances (or species) that dissociate (or break) in water to give hydrogen ions H+ (aq).
