h(W B+S A)=√(Kw/Kb × C) α propto (1/√C) ∴ h4 > h3 > h2 > h1

Q. Four solutions of $N H_{4} Cl$ are taken with concentrations $1 M, 0.1 M, 0.01 M$ and $0.001 M$ . Their degree of hydrolysis are $h_{1}, h_{2}, h_{3}$ and $h_{4} .$ What is the gradation of degree of hydrolysis?

$h_{1} > h_{2} > h_{3} > h_{4}$

$h_{1} = h_{2} = h_{3} = h_{4}$

$h_{4} > h_{3} > h_{2} > h_{1}$

None of these

$h (W B + S A) = \frac{K _{w}}{K _{b} \times C}$
$α \propto \frac{1}{C}$
$∴ h_{4} > h_{3} > h_{2} > h_{1}$

Q. Four solutions of NH4​Cl are taken with concentrations 1M,0.1M,0.01M and 0.001M. Their degree of hydrolysis are h1​,h2​,h3​ and h4​. What is the gradation of degree of hydrolysis?

h1​>h2​>h3​>h4​

h1​=h2​=h3​=h4​

h4​>h3​>h2​>h1​
