Question

in neutralisation reaction acid reacts with a base to form salt and water and a lot of heat is given out what type of change it is​

Answer 1

The heat (or enthalpy) of neutralization (ΔH) is the heat evolved when an acid and a base react to form a salt plus water. Q in the above equation is -ΔH and is expressed in kJ/mol of water. Neutralization reactions are generally exothermic and thus ΔH is negative.

hope it will help
