Predict whether each of the following is soluble in water or not.
a. potassium hydrogen sulfate, khso4 (used in wine making).
b. the polar molecular compound propylene glycol, ch3ch(oh)ch2oh (used in some antifreezes).
c. benzene, c6h6 (use to produce many organic compounds).

The soluble in water are a and b. c is not soluble in water

Explanation:

The water solubility of a compound, it depends its polarity (. KHSO4 has several polar molecules, actually it has ions charged positively like K and H, and charged negatively like sulfate (SO4-2). When it happens, molecules can do hydrogen bridges with water. It is because of above, KHSO4 can be used in wine making. Something similar happens with propylen glycol but in this case the polar part is OH- ions. Benzene has not polar parts. It is totally apolar compound.
