1. for each solute, identify the better solvent: water or carbon tetrachloride.

complete question:

For each solute, identify the better solvent: water or carbon tetrachloride.  C6H6, I2, Na2S, CH3OH

water → CH3OH and Na2S

Carbon tetrachloride → C6H6 and I2

Explanation:

To determine whether a solvent will dissolve a solute one need to know the polarity of the solvent and the solute. It is a known fact that polar solvent will dissolve polar solute while non polar solvent will dissolve non polar solute.

Water is a polar solvent so, it will dissolve most polar solute . carbon tetrachloride is a non polar solvent, it will dissolve non polar solute.

C6H6

C6H6 is a non polar solute so it will definitely dissolve better in carbon tetrachloride.

I2

I2 is a non polar solute therefore, it will dissolve better in carbon tetrachloride.

Na2S

Na2S is a polar solute it will definitely dissolve better in water.

CH3OH

CH3OH  is a polar solute it will dissolve better in water.
