Yes. A reaction does take place in neutralisation.
There is no specific thing. The chemical reaction is a result of the alkaline baking soda and the acidic vinegar neutralising each other.
Sulphurous acid is not a reaction (chemical or physical); the sulphurous acid (H2SO3) is a chemical compound.
The acid-base chemical reaction that is irreversible is the reaction between a strong acid and a strong base.
The chemical reaction in which an acid combines with a base is called a neutralization reaction. In this reaction, the acid and base react to form water and a salt.

chemical reaction
If you add more baking soda to a vinegar (acetic acid) and baking soda (sodium bicarbonate) mix there will only be a further reaction if there is more acetic acid available to react with the baking soda. If the acid was used up by the first amount of baking soda no further reaction can occur.
A chemical reaction that occurs between an acid and a base is called a neutralization reaction. In this reaction, the acid and base react to form water and a salt. It is characterized by the exchange of ions between the acid and the base.
This is a chemical reaction (dito change).

The chemical reaction between acetic anhydride and salicylic acid is called esterification. This reaction forms acetylsalicylic acid, which is commonly known as aspirin.
