Question

Water (H2O) is a polar solvent, and carbon tetrachloride (CCl4) is a nonpolar solvent. In which solvent is each of the following substances, found or used in the body, more likely to be soluble?

a. NaNO3, ionic
b. I2, nonpolar
c. sucrose (table sugar), polar
d. gasoline, nonpolar
e. vegetable oil, nonpolar
f. benzene, nonpolar
g. LiCl, ionic
h. Na2SO4, ionic

Answer 1

Answer:

a. NaNO3, ionic - water

b. I2, nonpolar - CCl4

c. sucrose (table sugar), polar - water

d. gasoline, nonpolar - CCl4

e. vegetable oil, nonpolar - CCl4

f. benzene, nonpolar -CCl4

g. LiCl, ionic - water

h. Na2SO4, ionic - water

Explanation:

Water is a polar substance. This means that it has the ability to dissolve other polar substances. Furthermore, water, even being made by covalent bonds, manages to dissolve ionic substances, because it is a molecule with a partial positive charge on one side, due to hydrogen, and a partial negative charge on the other side, due to the two molecules of oxygen. In this case, any polar or ionic substance has the ability to be dissolved in water, while any non-polar substance needs a non-polar liquid to be able to be dissolved, such as CCI4.
