Answer : when a beaker of acid is titrated with a basic solution, the acid becomes neutralized.

Explanation :

The reaction in which an acid reacts with a base forming a salt and water is known as neutralization reaction.

During neutralization reaction, acid and base neutralize each other.

That means they both lose their properties and completely new substances are formed which have different properties

For example, a reaction of acid HCl with base NaOH produces water and salt, NaCl.

HCl + NaOH \rightarrow NaCl + H2O

Therefore we can say that, when a beaker of acid is titrated with a basic solution, the acid is neutralized.
