Question

Which of the following compounds are soluble in $NaHC{O}_3$?

• A. Picric acid
• B.
• C.
• D.

Answer 1

Answer: (A), (B), (D)

The correct options are
A Picric acid
B
D

More acidic compounds will be soluble in $NaHC{O}_3$. The compounds in a,b,d are more acidic. So they are soluble in $NaHC{O}_3$.
But o-nitrophenol isn't that acidic to be soluble in $NaHC{O}_3$.
