Question

3. Which one of the following statements is false?@5pts a.) Carbon tetrachloride, CC14 is more miscible with hexane, C6H14 than it is with a polar solvent like methanol, CH30H. b.) The solubilities of solids in liquids may either increase or decrease as temperature increases. c.) Apparent percentage ionization of a polar covalent solvent in water increases as concentration of the solute increases. d.) A saturated solution contains the maximum amount of solute that can be dissolved in the solvent at that temperature.

Explanation / Answer

a) it is a true statement as ccl4 and hexane both are non polar hence both are miscible ,whereas methanol is a polar solvent

b) the solubility of solid increases in liquid as temperature increases , hence it is a false statement

c) it is false statement ,as polar covalent solvent are non ionizable in solvent

d) it is a true statement as a saturated solution defines the maximmum capacity of dissolvable solue
