Question

When $SO_2$ gas is passed into aqueous $Na_2CO_3$ the product(s) formed is (are)

• A. $NaHSO_4$
• B. $Na_2SO_4$
• C. $NaHSO_3$
• D. $Na_2SO_3$ and $NaHSO$

Answer 1

The Correct Option is C

The correct answer is C:\(NaHSO_3\)
On passing the \(SO _{2}(g)\) in the aqueous solution of \(Na _{2} CO _{3}\) we get \(NaHSO _{3}\) as product. \(Na _{2} CO _{3}+ H _{2} O +2 SO _{2}(g) \longrightarrow 2 NaHSO _{3}+ CO _{2}\)
