Classify the following as acid (or) base using Arrhenius concept HNO_3 (ii) Ba(OH)_2 (iii) H_3PO_4 (iv) CH_3COOH |
|
Answer» Solution :`HNO_3:` Nitric acid dissociates to give hydrogen IONS in water `THEREFORE HNO_3` is acid (ii) `BA(OH)_2`: Barium HYDROXIDE , dissociates to give hydroxyl ions in water `therefore Ba(OH)_2`is base. (iii) `H_3PO_4`: Orthophosphoric acid ,dissociates to give hydrogen ions in water. `therefore H_3PO_4` in acid. (IV) `CH_3COOH`: Acetic acid, dissociates to give hydrogen ions in water. `therefore CH_3COOH` is acid. |
