Video transcript

Everyone were asked to identify the following statement as correct or incorrect. The freezing point of a solution remains unchanged if more solute is added to the solution. Now we've learned that freezing point is a collective property and we know that collective properties are physical properties of solutions that only depend upon the number of solute particles in solutions and the identity of the solute does not matter. So if we add more of our salute into our solution, then the concentration of our solution will change. And because of this, this means the freezing point and other collective properties will also change. So this statement is going to be incorrect and we can go ahead and fix this by changing the following words into will change and this is going to be our final answer. So I hope that made sense and let us know if you have any questions.
