Question
Sodium carbonate is a basic salt because it is a salt of(a) strong acid and strong base(b) weak acid and weak base(c) strong acid and weak base(d) weak acid and strong base
Solution
Sodium carbonate is a basic salt because it is a salt of a weak acid and a strong base. So, the correct answer is (d) weak acid and strong base.
Here's why:
Sodium carbonate (Na2CO3) is formed by the neutralization reaction of sodium hydroxide (a strong base) and carbonic acid (a weak acid).
In water, sodium carbonate dissociates into sodium ions (Na+) and carbonate ions (CO3 2-). The carbonate ions can react with water to form bicarbonate ions (HCO3-) and hydroxide ions (OH-).
The presence of these hydroxide ions (OH-) makes the solution basic. Therefore, sodium carbonate is considered a basic salt.
