Discuss “the point of neutralization” in a titration of acid and base

Answer 1

Water has equal number of H⁺ and OH^- ions. The p^H of water is 7. The number of H⁺ ions = 1*10^-7 moles. Acidic solution is one in which the number of H⁺ ions are greater than that of water. Basic solution is one in which the number of H⁺ ions are lesser than that of water. Neutral solution is one in which the H⁺ ions are equal to that of water.

Titration is a method of determining the amount of reagent in a solution by reacting with another reagent which can neutralise the given reagent. The reagent being determined is called an analyte. And the reagent used to neutralise is called a titrant. Titrations can be of many types:

i) Acid - base titration

ii) Redox titration

iii) Gas phase titration

iv) Complexometric titration

The purpose of a titration is to determine the amount of analyte present in a given solution.

* Since the reaction is not pasted, please choose the correct type of titration.

Neutralization reaction is one in which the analyte is neutralised by the corresponding acid or base as a titrant. The titration is said to be complete when the stoichiometric number of moles of the titrant added is equal to the stoichiometric number of moles of the analyte present in the solution. This is also called as the end point or the equivalence point of titration.
