Question

What is the chemical equation for titration of $HCl + N{H_3}$ ?

Answer 1

In order to the question, first we will write the balanced reaction with their product which is given in the question. And then we will write the perfect equation for the titration of a given reaction.

Complete step by step solution:
Hydrochloric acid, HCL , a strong acid, will react with ammonia, NH3 , a weak base, to form aqueous ammonium chloride, NH4Cl , according to the following chemical equation:
$N{H_3}(aq) + HCl(aq) \to N{H_4}Cl(aq)$
In this particular reaction, the chloride anions, $C{l^ - }$ , act as spectator ions, which means that we can eliminate them from the balanced chemical equation to get the net ionic equation:
$N{H_3}(aq) + {H^ + }(aq) \to N{H_4}^ + (aq)$
It’s worth mentioning that because we are titrating a strong acid with a weak base, the pH of the resulting solution will be lower than 7 at equivalence point.
That is the case because this neutralized reaction produces the ammonium cation, $N{H_4}^ +$ , which acts as a weak acid in aqueous solution.
Titration is the process in which one solution is added to another solution such that it reacts under conditions in which the added volume may be accurately measured. It is used in quantitative analytical chemistry to determine an unknown concentration of an identified analyte.

Note:
A quantitative and volumetric technique, to determine the unknown concentration of a solution by the known concentration of a solution in the presence of an indicator is called Titration. Titration is a common laboratory method of using quantitative chemical analysis.
