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

Answer: (C)

$NaHSO_3$

Answer 2

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. $Na _{2} CO _{3}+ H _{2} O +2 SO _{2}(g) \longrightarrow 2 NaHSO _{3}+ CO _{2}$
