    Chemistry is an easiest subject among Physics, Mathematics and Chemistry in WBJEE Entrance Examination according to most of the students.

    In this article, you will get chapter notes of chapter Solutions including detailed information about all important topics like types of solutions, concentration of solutions, Henry’s law, Raoult’s law, Van’t Hoff factor, effective molarity etc.

    About 1-2 questions are always asked from this topic in WBJEE examination.

    These chapter notes are prepared by Subject Experts of Chemistry after the detailed analysis of the latest syllabus of WBJEE Entrance examination.

    To make understand the concepts to WBJEE aspirants, some previous year solved questions are also included in these notes.

    WBJEE Solutions Question 1

    Solution 1:

    WBJEE Solutions Solution 1

    Hence, the correct option is (a).

    Important Questions and Preparation Tips – Atomic Structure

    Question 2:

    WBJEE Solutions Question 3

    Solution 2:

    WBJEE Solutions Solution 3

    Hence, the correct option is (b).

    Important Questions and Preparation Tips – Solid State

    Question 3:

    If P and Po are the vapour pressure of the pure solvent and solution and n1 and n2 are the moles of solute and solvent respectively in the solution then the correct relation between P and Po is

    WBJEE Solutions Question 1

    Solution 3:

    According to Roult’s law we have:

    WBJEE Solutions Solution 1

    Hence, the correct option is (C).

    Important Questions and Preparation Tips - Phenols

    Question 4:

    Lowering of vapour pressure is highest for

    (a) 0.1 M BaCl2

    (b) 0.1 M glucose

    (c) 0.1 M MgSO4

    (d) urea

    Solution 4:

    Lowering of vapour pressure is directly proportional to the Van't Hoff factor (i).

    For BaCl2,i = 3 (maximum)

    Thus, BaCl2 has highest value relative lowering of vapour pressure.

    Hence, the correct option is (a).
