For each solute, identify the better solvent: water or carbon tetrachloride.
C6H6, I2, Na2S, CH3OH
Answer:
We know that like dissolves like. Polar solutes dissolve in polar solvents and nonpolar solutes dissolve in non-polar solvents.
Here, water is a polar solvent and carbon tetrachloride is a non-polar solvent.
C6H6:
C6H6 is a non-polar solute, so that it dissolves in carbon tetrachloride solvent.
I2:
I2 is a non-polar solute, so that it dissolves in carbon tetrachloride solvent.
Na2S:
Na2S is a polar solute, so that it dissolves in water solvent.
CH3OH:
CH3OH is a polar solute, so that it dissolves in water solvent.
