Question

Baking soda is which type of salt?

• A. Basic salt
• B. Acidic salt

Answer 1

Answer: (B)

Explanation:

• Baking soda is a basic salt.
• The chemical formula for baking soda is $NaHC{O}_3$.
  $NaHC{O}_3$ is a salt of a weak acid, $H_{2}C{O}_3$, and a strong base, $NaOH$. Since carbonic acid is a weak acid, it remains undissociated.
• Hence, the solution becomes basic due to the presence of additional OH- ions produced by hydrolysis.

Hence, option (B) is correct.
