Question

What happens to the nature of (a) acids and (b) bases during neutralization reaction? How do we establish that heat is evolved in neutralization reaction? (plz answer fast)

Answer 1

Answer:

a)During neutralization reaction the the base can neutralize an acid and destroy its basicity similarly the acid reacts with the base to from pH value of 7 which shows that the substance is neutral.

b) in a neutralisation reaction, heat is always produced, or evolved.this heat evolved when an acid and a base react to form salt and water.The evolved heat also raises the temperature of the reaction mixture.
