Question

Two aqueous solutions are found to have different freezing points: Solution A freezes at 260 K and Solution B freezes at 250 K. Which statement is true? Select one: Solution A has a higher osmolar concentration, Solutions A and B have equal osmolar concentrations, Solution B has a higher osmolar concentration The identity of the solute must be known to compare freezing points. The volume of the solutions must be known before the freezing points can be compared Which of the following is the correct order for increasing boiling point? Select one: water $ 1.0 M CUNO, (aq) < 1.0 M Mgør, (aq) 1.0 M MgBrą (aq) < 1.0 M CUNO, (aq) swater water < 1.0 M MgBr, (aq) < 1.0 M CUNO, (aq) 1.0 M CUNO, (aq) < 1.0 M MgBr_caa) water

Answer 1

Solutions :- o Depression in freezing point is a colligatione property. more the concentration ce. more the number of solute Particks, more will be depression ñ freezing point Since freezers fornt af B( 2501c) is less then the freezing foint af A (260 k) it means Concentrates as soluters B is more than that of True statiment is. solution is has a highes osmolar Concentrations, ② the correct order of increasing boiling point is I water <1.0m CanoBags <1.0 mmg bor er Explanaty! - 1.om Ca Nu Ž 2.0 mole Partills - rom my Borz £ 3.0 mole parting ( CuNB & my bors are electrolyte) and elevation in boiling point is a colligati Property
