Define an ideal solution and write one of its characteristics.
Fill in the blanks by choosing the appropriate word/words from those given in the brackets:
Ideal solutions obey ………. law and they …………. form azeotropic mixtures.
(Henry’s, aldol condensation, absence, do not, ohm, Raoult’s, increases, common ion effect, easily, three, solubility product, ohm-1, two, four, ohm-1, cm2, Cannizzaro, ohm-1 cm-1, zero, decreases, presence)
Assertion: An ideal solution obeys Raoults Law.
Reason: In an ideal solution, solvent – solvent as well as solute – solute interactions are similar to solute-solvent interactions.
