6-2.Equilibrium-II (Ionic Equilibrium)
medium

$0.1\,M$ એસિટીક એસિડ $1$$\%$ આયનીકરણ થાય છે જો તેનું આયનીકર $10$ ઘણું થાય તો તેની સાંદ્રતા કેટલી થાય ?

A

$0.001$

B

$0.01$

C

$0.0001$

D

$0.1$

Solution

$Ka = C\alpha ^2$

${K_a} = 0.1 \times {\left( {\frac{1}{{100}}} \right)^2} = {10^{ – 5}}$

જો  તે $10$$\% $ આયનીકરણ થાય તો સાંદ્રતા

${10^{ – 5}} = C \times {\left( {\frac{{10}}{{100}}} \right)^2}\,\,\, \Rightarrow \,\,\,\,{10^{ – 5}} = C \times {10^{ – 2}}\,\,\,\,\,\,\therefore \,\,\,\,C = {10^{ – 3}}\,\,i.e.\,\,0.001\,M$
