A) 0.2 M urea and 0.2 M KCl
B) 0.1 M urea and 0.2 M \[CaC{{l}_{2}}\]
C) 0.1 M KCl and 0.1 M \[{{\operatorname{Na}}_{2}}S{{O}_{4}}\]
D) 0.1 M \[Ca{{\left( N{{O}_{3}} \right)}_{2}}\] and 0.1 M \[{{\operatorname{Na}}_{2}}S{{O}_{4}}\]
Correct Answer: D
Solution :
Solutions have same number of ions will exert equal osmotic pressure and expected to show isotonic. \[Ca{{(N{{O}_{3}})}_{2}}\rightleftharpoons \,\,C{{a}^{2+}}+2NO_{3}^{-}\,\,\,\,\,\,\,\,i\,\,=\,\,3\] \[N{{a}_{2}}S{{O}_{4}}\rightleftharpoons \,\,N{{a}^{+}}\,+\,\,SO_{4}^{--}\,\,\,\,\,\,\,\,\,\,\,\,\,\,i=3\]You need to login to perform this action.
