MCQ
Which ion is responsible for the acidity of aqueous solutions?
- AHydroxide ion $\left( OH ^{-}\right)$
- BSodium ion $\left( Na ^{+}\right)$
- ✓Hydronium ion $\left( H _3 O ^{+}\right)$
- DChloride ion $\left( Cl ^{-}\right)$
✓
Answer
Correct option: C.
Hydronium ion $\left( H _3 O ^{+}\right)$
(c) Hydronium ion $\left( H _3 O ^{+}\right)$
Explanation : Acidity in aqueous solutions is primarily due to the presence of hydronium ions $\left( H _3 O ^{+}\right)$. These ions are formed when an acid donates a proton $\left( H ^{+}\right)$to water.
