Define solution, solvent and solute.

Define Solvent

Equal masses of a solute are dissolved in equal amount of two solvents A and B respective molecular masses being M_(A) and M_(B) . The relative lowering of vapour pressure of solution in solvent A is twice that of the solution in solvent B. If the solutions are dilute , M_(A) and M_(B) are related as

The characterstic property of solution is (a) formation of solution is physical change (b) solute and solvent in the solution can be separated by filteration (c) solute and solvent in the solution can be separated by decantation (d) solution can be represented with a chemical formula

Define Heat of solution. Give an example.

Write the steps you would use for making tea. Use the words given below and write the steps for making tea. Solution,solvent,solute,dissolve,soluble,insoluble,filtrate and residue.

The correct process is a) add solvent more to dilute a solution b) add solution more to dilute a solution c) add solute more to concentrate a solution d) add solvent more to concentrate a solution.

7g of a solute are dissolved in 200 g of a solvent (mol. Wt. 78) to prepare a solution. At a certain temperature dry air is sent into a solution and solvent continuously. The loss is weights of containers containing solutions and solvent are 0.975 g and 0.025 g. Calculate the molar mass of solute.

Identify solute and solvent in the following solutions. 1 . Aerated drinks(cool drinks) 2 . Tincture of Iodine 3 . Lemon water
