The class is set for class 12 students.And the class is all about solutions .There are different types of solutions and the physical and chemical properties related to the solutions.Some mathematical related problems are also being discussed as there are some important rules like Roults law,Henrys law etc are being mentioned.Through this the student will be able to get a knowledge about the different properties associated with aliquid especially a solution .And they could notice the real life application of solutions in many ways.The properties like density ,surface tension, fluidity, etc are being discussed.And the assignment regarding this class is to practice a lot of mathematical problems from this chapter.Molarity, Molality,mole fraction, mass percentage etc are the main equations . Different colligative properties is one among the important portionsas there derivation related to finding the molecular mass is being derived in text in detail.As if there are of the total solution is all about
