Question

Does the addition of distilled water to an acid-base titration affect the end-result?

Answer 1

Arrhenius is one of the concepts for acid and bases. The world’s first chemist to talk about acid and bases is Swedish chemist Arrhenius. Depending on his concept and limitations later, so many concepts are developed. Concept of acids and bases is the birthplace of Arrhenius. Followed by Arrhenius, the concept of acids and bases discusses Bronsted and Lowry in the world.

Complete answer:
The addition of distilled water is affecting the concentration of the acid but it should not be acid-base titration at the end- result. Because the addition of distilled water is not able to affect the moles of acid and base in the acid-base titration. Hence, the addition of distilled water to an acid-base titration should not be acid-base titration at the end result.
According to the above discussion, we conclude that addition of distilled water to an acid-base titration is not able to affect the end result.

Note:
In general, the pH value of all acids is in between ${\text{0}}{\text{.9}}$-$6.9$ and all the bases are in between $7.1 - 14.0$. But, Arrhenius’s theory has some limitations. One of the main limitations is not explaining the behaviour of acids and bases in non-aqueous solvents such as acetone etc, It is not able to explain the acid which doesn’t contain hydrogen and bases don’t contain hydroxyl ions in the formula. Ammonia is a well-known base that is not acceptable as the base in the Arrhenius base. These limitations are overcome by further coming theories like Bronsted and Lowry’s concept of acids and bases.
