Question
Write the main difference between an acid and a base. With the help of suitable examples the term neutralization and the formation of:
- Acidic
- Basic
- Neutral salts.
✓
Answer
Acid | Base | |
1 | An acid produces H+ ions in aqueous solution. | A base produces OH-ions in aqueous solution. |
2 | Acids are sour in taste. | Bases are bitter in taste. |
3 | Acids change the colour of blue litmus to red. | Bases change the colour of red litmus to blue. |
- $\text{Acidic}-\text{NH}_4\text{OH}\ +\ \text{HCl}\xrightarrow{ \ \ \ \ \ \ \ }\text{NH}_4\text{Cl}+\text{H}_2\text{O}$
- $\text{Basic}-\text{NaOH}\ +\ \text{H}_2\text{CO}_3\xrightarrow{ \ \ \ \ \ \ \ }\text{Na}_2\text{CO}_3+\text{H}_2\text{O}$
- $\text{Neutral}-\text{KOH}\ +\ \text{HNO}_3\xrightarrow{ \ \ \ \ \ \ \ }\text{KNO}_3+\text{H}_2\text{O}$
