Question

Which gas is formed when vinegar reacts with baking soda and how can we test the
presence of that gas?

Answer 1

Answer:

carbondioxide

Explanation:

The solid baking soda was placed in liquid vinegar producing carbon dioxide gas, which is evident because of the formation of bubbles in the foaming mixture.

Answer 2

When baking soda is mixed with vinegar, something new is formed. The mixture quickly foams up with carbon dioxide gas. If enough vinegar is used, all of the baking soda can be made to react and disappear into the vinegar solution.

The reaction is:

Sodium bicarbonate and acetic acid reacts to carbon dioxide, water and sodium acetate.
