can the reaction between alkali and acid be reversed
Some chemical reactions can be reversed, but most cannot.
no.
No.
no
Proton-Transfer: reactions favor the production of the weaker acid and weaker base.
Almost any reaction can involve an acid; the most common is the acid-base or neutralisation reaction.
A reaction between a base and an acid is a neutralization reaction with the formation of a salt.
Salts are the result of a neutralization reaction between an acid and a base.
Baking powder (baking soda + some acid salts) will release CO2 (carbon dioxide gas) when placed in water. So, even though, in theory, all reactions are reversible, it is not likely that baking powder in water is reversible once the CO2 gas has formed.

These reactions are irreversibles.
Reversible Reaction
Acid + Base = Salt +Water
Acid-Base Reactions.
Such reactions are called neutralization reactions.

No, most of them are just acid base reaction and not followed by oxidation reduction reaction.
Acid-base reactions are chemical reactions that occur only between an acid and a base. These are examples of single-displacement reactions. An acid is loosely described as something, whether it be an element or a compound, combined with hydrogen to form a (larger) compound. A base is loosely described as a compound or element combined with OH (Hydroxide). An acid-base reaction always yields H2O.
Since protons are always transferred in the Arrenhius concept, all Arrhenius acid/base reactions are also Bronsted-Lowry acid/base reactions.
