6-2.Equilibrium-II (Ionic Equilibrium)
medium
દ્રાવણ માટે $K = 4.41 \times 10^{-5}$, $C = 0.1 \,M$ તો $\alpha$ = ?
A
$2.1 \times 10^{-2}$
B
$4.41 \times 10^{-4}$
C
$1.5 \times 10^{-1}$
D
$2.1 \times 10^{-1}$
Solution
${\text{K}} = {\text{C}}{\alpha ^{\text{2}}}\,\,\,\,\,\,\,\alpha = \sqrt {\frac{K}{C}} = \sqrt {\frac{{4.41 \times {{10}^{ – 5}}}}{{0.1}}} = 2.1 \times {10^{ – 2}}$
