Q. NH4​CN is a salt of weak acid HCN(Ka​=6.2×10−10) and a weak base NH4​OH(Kb​=1.8×10−5). A one molar solution of NH4​CN will be 5722 239 Equilibrium Report Error A

neutral

17% B

strongly acidic

13% C

strongly basic

20% D

weakly basic

50%

Solution:

Since Kb​>Ka​, the solution will be slightly basic.
