For each solute, identify the better solvent: water or carbon tetrachloride. C6H6, I2, Na2S, CH3OH
The principle of “like dissolves like” explains that polar solutes dissolve in polar solvents, while non-polar solutes dissolve in non-polar solvents. In this case, water acts as a polar solvent, and carbon tetrachloride is a non-polar solvent.
C6H6: Being a non-polar solute, C6H6 dissolves in carbon tetrachloride, which is also non-polar.
I2: Iodine (I2) is a non-polar solute and thus dissolves in carbon tetrachloride.
Na2S: Sodium sulfide (Na2S) is a polar solute, so it dissolves in water, a polar solvent.
CH3OH: Methanol (CH3OH) is a polar solute, so it dissolves in water, which is also polar.
