Reaction Explained Simply

The reaction is known as an 'Acid-Base' reaction.

Baking soda is a base, and vinegar is an acid. Vinegar isn't just an acid, it is an acid in water, which is important.

The water in the vinegar acts as a host where the base and acid react. During the reaction, when the baking soda is mixed with the vinegar, the baking soda (Base) takes a proton from the vinegar (Acid). The reaction causes the baking soda to transform into water and carbon dioxide. The carbon dioxide is a gas which is released during the reaction, which gives it the bubbling effect, and it expands which will blow up balloons as you have probably seen in some experiments and demonstrations.
