Which one is strongest electrolyte in the following
1 \(NaCl\)
2 \(C{H_3}COOH\)
3 \(N{H_4}OH\)
4 \({C_6}{H_{12}}{O_6}\)
Explanation:
(a)\(NaCl\), being a salt, is a strong electrolyte.
Ionic Equilibrium

If \(\alpha \) is the degree of ionization, \(C\) the concentration of a weak electrolyte and \({K_a}\)the acid ionization constant, then the correct relationship between \(\alpha ,\,\,C\) and \({K_a}\)is
1 \({\alpha ^2} = \sqrt {\frac{{{K_a}}}{C}} \)
2 \({\alpha ^2} = \sqrt {\frac{C}{{{K_a}}}} \)
3 \(\alpha = \sqrt {\frac{{{K_a}}}{C}} \)
4 \(\alpha = \sqrt {\frac{C}{{{K_a}}}} \)
Explanation:
(c) According to the Ostwald’s dilution formula \({\alpha ^2} = \frac{{K(1 - \alpha )}}{C}\). But for weak electrolytes \( \alpha \) is very small. So that \((1 - \alpha )\) can be neglected. So that \(\alpha = \sqrt {\frac{{{K_a}}}{C}} \).
