Assertion: Aqueous solution of CH3COONH4 is found to be neutral
Reason: This salt does not undergo hydrolysis
A.Both assertion and reason are correct and reason is the correct explanation for assertion
B.Both assertion and reason are correct but reason is not the correct explanation for assertion
C.Assertion is correct but reason is incorrect
D.Both assertion and reason are incorrect
Solution
Ammonia acetate is a chemical compound with formula CH3COONH4 . It is basically a white solid which can be derived from the reaction of ammonia and acetic acid. Moreover, it is quite soluble in water and its solubility increases with an increase in the temperature.
Complete step by step answer:
Ammonium acetate also known as spirit of Mindererus is an ammonium salt obtained by reacting ammonia with acetic acid. It is basically a white crystalline solid with acetous odor. It can further be obtained by two methods:
By neutralizing acetic acid with ammonium carbonate
By saturating glacial acetic acid with ammonia
Moreover, it functions as a precursor to acetamide. The reaction is as shown:
NH4CH3CO2→CH3CONH2+H2O
Now, ammonium acetate is a salt of weak acid i.e. acetic acid and weak base ammonia. On hydrolysis, it produces ammonia and acetic acid both of which have an approximately equal degree of dissociation. Therefore, it gives an equal number of hydrogen ions and hydroxide ions and hence, its aqueous solution is found to be neutral.
So, the given assertion is correct but the reason is incorrect.
Hence, option C is correct.
Note: Ammonium acetate is used in making explosives, in manufacturing vinyl plastics, in analytical chemistry as a reagent, in agricultural products etc. Moreover, inhalation may cause stomach and respiratory tract irritation and may cause eye and skin rashes too,
