Question
Define an acid salt and a normal salt.
✓
Answer
Acid Salt : The salt formed by the partial replacement of the replacable hydrogen atoms of an acid molecule by a metallic or ammonium ion is called acid salts.
For example : $NaHSO_{4 ,}Na_2HPO_4$.
Normal Salt : The salt formed by replacement of all the replacebale hydrogen atoms of an acid by metallic or ammonium ions is called a normal salt.
For example : $NaCI , Na_2SO_4$.
For example : $NaHSO_{4 ,}Na_2HPO_4$.
Normal Salt : The salt formed by replacement of all the replacebale hydrogen atoms of an acid by metallic or ammonium ions is called a normal salt.
For example : $NaCI , Na_2SO_4$.
