A solution of ammonium cyanide is :
Correct answer: B. alkaline in nature
- A. acidic in nature
- B. alkaline in nature
- C. neutral in nature
- D. amphoteric in nature
Explanation
A solution of NH4CN is alkaline because CN- is more strong conjugate base than NH4 + , conjugate acid. The hydrolysis of CN- proceeds more that of NH4+.

About Acids, Bases and Salts
Acid and base behaviour is explained through the Bronsted-Lowry transfer of protons and the Lewis donation or acceptance of electron pairs. The topic includes pH, pOH, ionisation and water equilibrium, plus salt formation and hydrolysis, where a salt solution may become acidic, basic or neutral.
