Select ALL! the solutes below that would be soluble in a polar solvent (like water).

Fofino [41]

Answer:

K2SO4, NH3, HOCI, HCI, CH3NH2, SiCl4, CO2, CH20

Explanation:

Substances are soluble in water when they are ionic or polar covalent substances.

If we look at the substances listed, K2SO4 is ionic while NH3, HOCI, HCI, CH3NH2, SiCl4, CO2, CH20 all contain polar covalent bonds which accounts for their water solubility.

Hence ionic and polar covalent substances are soluble in a polar solvent such as water.
