Practice CBSE Class 12 (Science) Reactions in Aqueous Solution 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:Adding a non-volatile solute to a solvent makes its vapour pressure:Properties depending on the number of solute particles are called:The word colligative comes from Latin words meaning to bind:How many colligative properties are listed for solutions?Adding a solute changes the freezing point of the solvent by:Adding a solute changes the boiling point of the solvent by:Raoult found the lowering of vapour pressure depends only on:A membrane passing solvent but not solute is called:Solvent flowing through a semipermeable membrane into solution is:The pressure that just stops the osmotic flow is called:Osmosis carries solvent from a solution that is dilute to one:Osmotic pressure is especially useful for finding the molar mass of:Two solutions with the same osmotic pressure are called:Between two isotonic solutions separated by a membrane, osmosis is:Normal saline solution used for injection is sodium chloride at:A solution stronger than normal saline makes blood cells:A solution stronger than the cell contents is called:A solution weaker than the cell contents is called:Cells placed in a hypotonic solution will:Applying more than the osmotic pressure to a solution gives:Reverse osmosis is used to treat which kind of water?Colligative property equations are corrected using the factor of:
