When potassium cyanide reacts with water, will the resulting solution be acidic, alkaline or neutral? Justify your answer. |
|
Answer» KCN is a salt of a strong base and weak acid. It undergoes hydrolysis when dissolved in water to form weak acid HCN and strong base KOH. HCN is a weak acid because it gives less H+ ions in the solution while KOH is strong electrolyte and remains completely dissociated. Therefore, the resulting solution contains more OH– ions and it is therefore alkaline. |
