Question
Which of the following aqueous solutions should have the highest boiling point?
Options
1.0 M NaOH
1.0 M Na2SO4
1.0 M NH4NO3
1.0 M KNO3
Solution
1.0 M Na2SO4
Explanation:
In 1.0 M Na2SO4 solution vant Hoff factor, i > 1 and is maximum when compared with the other three given electrolytes. So, the extent of dissociation in case of 1.0 M Na2SO4 would be highest yielding maximum no. of ions as compared to the other given electrolytes in their 1.0 M solutions.
