Formation of a solution from two componets can be considered as : (i) pure solvent `rarr` separated solvent molecules, `/_\H_(1)` (ii) Pure solute `rarr`separated molecules,`/_\H_(2)` (iii) separated solvent and solute molecules`rarr`solution, `/_\H_(3)` solution so formed will be ideal if :
A
`/_\H_("soln")=/_\H_(1) + /_\H_(2) +/_\H_(3)`
B
`/_\H_("soln")=/_\H_(1) + /_\H_(2) -/_\H_(3)`
C
`/_\H_("soln")=/_\H_(1) -/_\H_(2) -/_\H_(3)`
D
`/_\H_("soln")=/_\H_(3) - /_\H_(1) -/_\H_(2)`

9.8 g of H_(2)SO_(4) is present in two litres of a solution. The molarity of the solution is,
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
In the depression of freezing point experiment, it is found that (a) The vapour pressure of the solution is less than that of pure solvent (b) The vapour pressure of the solution is more than that of pure solvent (c) Only solute molecules solidify at the freezing point (d) Only solvent molecules solidify at the freezing point
Solubility is the measurement of amount of solute that dissolves in a solvent at a certain temperature. Factors that effect the solubility are (i) Temperature (ii) Size of the solute particles (iii) Stirring of a solution
An antifreeze solution is prepared from 222.6g of ethylene glycol [(C_(2)H_(6)O_(2))] and 200g of water (solvent). Calculate the molality of the solution.
(A) : Grignard synthesis is always carried out in ethereal solution. (R) H_2O is polar solvent .
When some amount of non-volatile solute is dissolved in a solvent to prepare a dilute solution, the vapour pressure of the solvent is lowered and it is directly proportional to the mole fraction of solvent in the solution . Relative lowering in vapour pressure is equal to mole fraction of solute . Elevation in boiling point of solvent is a collgative property like lowering in vaour pressure of solvent in solution , K_(b) i.e., molal elevation constant is calculated by the formula, K_(b)=DeltaT_(b)// molality and also by the expression, K_(b)=RT_(b)^(2)//1000l_(v) where T_(b) is boiling point of solvent and I_(v) is latent heat of vapourisation for 1 gm solvent . Abnormal elevation is boiling point =iX elevation in boiling point in ideal solution where i=van't Hoff factor Lowering in vapour pressure in an experiment was found to be x mm of Hg. It is : Lowering in vapour pressure in an experiment was found to be x mm of Hg. It is
