NH₄CN is a salt formed from weak base NH₄OH and weak acid HCN so that it undergoes complete hydrolysis
<h3>Further explanation</h3>The hydrolysis process is a term used for the reaction of substances with water
There are 3 types of hydrolysis salts
1.Salt from strong acids and strong bases does not undergo hydrolysis so that the pH of the neutral solution = 7
2.Salt from strong acids and weak bases (pH <7) or from strong bases and weak acids (pH> 7) will be partially / partially hydrolyzed
3.Salt from weak acids and weak bases (pH depends on the value of Ka and Kb) will be completely hydrolyzed
NH₄CN is a salt formed from weak base NH₄OH and weak acid HCN so that it undergoes complete hydrolysis
NH₄OH + HCN⇒NH₄CN+H₂O
Can be formulated :
Ka> Kb then [H +]> 7 and pH <7 ⇒ acidic
Ka <Kb then [H +] <7 or pH> 7 ⇒alkaline
Ka = Kb then pH = 7 ⇒neutral
