Question

Q.4 First solution is 1m aqueous solution of glucose and second solution is lm aqueous solution of Sucrose. Which of the following is correct? o . (a) First solution has more boiling point than second. (b) First solution has less freezing point than second Both solutions have equal boiling points and equal freezing points.. a fost Both (a) and (b)​

Answer 1

both is the solution a and b

Answer 2

Glucose and Sucrose both have same boiling and freezing point

Explanation:

• Glucose and Sucrose both do not dissociate in aqueous solution so both van't hoff factor is 1

• Both have same molar concentration so both show same colligative property  which results in having same boiling  and freezing point.

• Van't hoff factor value become less or more than 1 depending on their association and dissociation property.

• This value then determine or influence the colligative property
