Question

Explain how molarity changes with temperature?

Answer 1

Simplified, molarity is affected by temperature because morality is simply a measure on the volume of a particular solution, and the volume of a substance will be negatively or positively affected by changes in temperature. In theory, volume will increase when temperature increases, a reciprocal effect of molarity.

Answer 2

Molarity of a solution is number of moles dissolve in a litre of volume...If we change the temperature , moles of solute in a solution doesnt get affected , it means moles of solute remain constant...

But temperature affect the volume of the solutio...

As Molarity ,

M = ( no. of moles of solute ) / (volume of solution in litre )

Molarity depends inversely on Volume...

So , On increasing temperature , volume of the solution increases...As a result molarity decreases...On decreasing temp , Molarity of solution increases...
