Question

Give balanced equations for the following reactions of synthesis involving formation of:
An acid - from sulphur dioxide gas
An alkali - from a basic oxide - sodium oxide

Answer 1

1) An acid - from sulphur dioxide gas

Ans:$\sf{SO_3+H_2O \rightarrow H_2SO_4}$

2) An alkali - from a basic oxide - sodium oxide

Ans: To obtain alkali from $\sf{Na_2O}$ dissolve basic oxide in water.

$\sf{Na_2O + H_2O \rightarrow 2NaOH}$

Answer 2

Answer:

Hello Dear User__________

Here is Your Answer...!!

Explanation:

Reactions  of acid with SO₂

2 HNO₃ + SO₂ → H₂SO₄ + 2 NO₂  

Reactions  of alkali metal with  basic oxide to form Sodium oxide

Na₂O + H₂O → 2 NaOH

Hope it is clear to you.
