What happens when an acid and a base come in contact with each other? Choose as many correct answers as are applicable. a. The pH level decreases for both the acid and the base.

b. They create a chemical reaction.

c. They neutralize each other.

d. They produce salt and water.

e. The pH level increases for both the acid and the base.

B, D, C are correct

Explanation:

neutralization reaction is a chemical reaction

because new substances are formed (salt and water).

D the product of neutralization is salt and water

C, they neutralize themselves in the sense that the acid with low pH will help to increase it's pH power by reacting with a base that has a high pH decreasing it's pH level

The correct answers are B D And C

An alkali is also known as a base. When an alkali(base) reacts with an acid neutralisation occurs.
As a result of this chemical reaction, salt and water is produced.
