Practice CBSE Class 12 (Science) Ideal and Non-Ideal Solutions in the app →The mole fraction of urea ($M = 60\,\text{g/mol}$) in an aqueous solution containing $6\,\text{g}$ of urea in For an ideal solution containing two volatile liquids A and B, Raoult's law gives the total vapour pressure asOsmotic pressure of a dilute solution is expressed by van't Hoff's equation as:Two solutions are said to be **isotonic** if they:If $\mathrm{NaCl}$ undergoes complete dissociation in water, the van't Hoff factor $i$ is:Desalination of sea water is best carried out by:The MOLARITY of a solution containing 58.5 g NaCl dissolved in 1 L of solution is:HENRY'S LAW states that at constant temperature:A MINIMUM-BOILING azeotrope arises from:Which of these is NOT a colligative property?Salt is sprinkled on icy roads in cold countries to:The van't Hoff factor (i) for sodium chloride (NaCl) in water is approximately:Solutions obeying Raoult's law over the whole range are:For an ideal solution, the heat absorbed or evolved on mixing is:The volume of an ideal solution equals the sum of the:An ideal solution forms when A-B forces against A-A and B-B are:Which pair forms a nearly ideal solution?A solution failing Raoult's law over the full range is:A vapour pressure higher than predicted means the solution shows:A vapour pressure lower than predicted means the solution shows:In positive deviation the A-B interactions are, against the rest:In a positive deviation the molecules find it easier to:A mixture of ethanol and acetone shows:Acetone added to ethanol breaks some of its:Carbon disulphide added to acetone gives a solution showing:In negative deviation the A-B interactions are, against the rest:A mixture of phenol and aniline shows:Chloroform and acetone form a hydrogen bond, so the vapour pressure:Binary mixtures boiling at a constant temperature are called:The components of an azeotrope cannot be separated by:A large positive deviation produces an azeotrope that is:A large negative deviation produces an azeotrope that is:Distilling an ethanol and water mixture stops at about:The nitric acid and water azeotrope holds nitric acid at about:
