Q26 of 30 Page 246

Note : A statement of assertion followed by a statement of reason is given. Choose the correct option out of the options given below each equation.

Assertion : Molarity of a solution in liquid state changes with temperature.


Reason : The volume of a solution changes with change in temperature.


Molarity is given by,

M= no. of moles/ volume of the solution.


As volume is directly proportional to temperature and inversely proportional to molarity, therefore molarity and temperature are inversely proportional.


The molarity of a solution can be changed by changing the volume. So this makes assertion and reason both correct and reason is the correct explanation.
