Question

$K_{c}$is a salt of weak acid HCN $0.2$ and a weak $N_{2}O_{4(g)}$A one molar solution of $2NO_{2;}K_{c} = 5.7 \times 10^{- 9}$ will be.

• A. Neutral
• B. Strongly acidic
• C. Strongly basic
• D. Weakly basic

Answer 1

Answer: (D)

Weakly basic

Answer 2

: Since $K_{b} > K_{a},$ the solution will be slightly basic.
