Question
Write the main difference between an acid and a base. With the help of suitable examples the term neutralization and the formation of:
  1. Acidic
  2. Basic
  3. 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.
Neutralization - A reaction of an acid with a base to produce salt and water.
  1. $\text{Acidic}-\text{NH}_4\text{OH}\ +\ \text{HCl}\xrightarrow{ \ \ \ \ \ \ \ }\text{NH}_4\text{Cl}+\text{H}_2\text{O}$
  2. $\text{Basic}-\text{NaOH}\ +\ \text{H}_2\text{CO}_3\xrightarrow{ \ \ \ \ \ \ \ }\text{Na}_2\text{CO}_3+\text{H}_2\text{O}$
  3. $\text{Neutral}-\text{KOH}\ +\ \text{HNO}_3\xrightarrow{ \ \ \ \ \ \ \ }\text{KNO}_3+\text{H}_2\text{O}$
