| What is more expedient to wash dishes after experiments with aniline: a) water; b) sodium hydroxide solution; c) diluted hydrochloric acid solution. Why?
It is more expedient to wash the dishes with those in which the pollutant dissolves better. Therefore:

b) Sodium hydroxide solution is not suitable – aniline is also poorly soluble in it;
c) A dilute solution of hydrochloric acid – suitable, because in this case, a water-soluble salt of phenylammonium chloride (aniline hydrochloride, aniline hydrochloric acid) is formed by the reaction:
C6H5NH2 + HCl = [C6H5NH3+]Cl–
