Question

). Why is the solution of sodium hydrogencarbonate mildly basic in nature?​

Answer 1

Explanation:

NaHCO3 is a salt of a weak acid, H2CO3, 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.

Answer 2

Answer:

Solution of sodium hydrogen carbonate is mildly alkaline due to the formation of carbonic acid and hydroxide ion.
