Difference between acid and alkali (other than indicator):
| Acid | Alkali |

| Acids are compounds which contain one or more hydrogen atoms and when dissolved in water, produce hydronium ions [H3O+] as the only positively charged ions. | An alkali is a basic hydroxide which when dissolved in water produces hydroxyl [OH-] ions as the only negatively charged ions. |
| Acids have a sour taste. | Alkalis have a sharp and bitter taste. |
| Acids have pH value less than 7. | Alkalis have pH value greater than 7. |
