Question

what would happen when a pinch of washing soda is added to dilute sulphuric acid?

Answer 1

hey...

Washing soda is sodium carbonate.​Sodium carbonate reacts with sulphuric acid to form sodium sulphate, water and carbon dioxide.

Answer 2

Explanation:

When a pinch of washing soda is added to dilute sulphuric acid then there will be formation of sodium sulphate, water and carbon dioxide. The reaction will be as follows.

            $Na_{2}CO_{3}.10H_{2}O + H_{2}SO_{4}(aq) \rightarrow Na_{2}SO_{4}+ 11H_{2}O(l)+ CO_{2}(g)$

Here, sulphuric acid is acting as a dehydrating agent and hence it will remove water molecules from the washing soda.
