Teresa Anderson · Answer 1

Lithium iodide, sodium fluoride and potassium iodide are more likely to undergo dissolution in water.

Explanation:

Water is a polar substance, which means that it will be a good solvent for other polar substances and salts.

LiI, NaF and KI are all salts that easily dissociate in water to produce ions. The ions will be surrounded by water molecules (solvatation) due to electrostatic interactions.

Heptane and octane are both non-polar substances that have no significant charges to interact with water molecules. Therefore, this substances will not dissolve in water.
