Which of the following is not a characteristic of a neutralization reaction?

Temperature of the reaction mixture decreases.

The correct answer is option 1. Temperature of the reaction mixture decreases.

During the neutralization process, salt is created as a new substance. Salt can be neutral, acidic, or basic. Neutralization can therefore be explained as follows: When an acid and a base interact, the neutralization process takes place. As a result of the evolution of heat, salt and water are produced. The reaction mixture's temperature is increased by the heat that is released.
