Rank the solutions in order of increasing electrical conductivity, based on the fact that the greater the number of ions in solution, the greater the conductivity. Molecular Compounds: Usually, molecular compounds are insoluble in water, but are soluble in organic solvents. Add about 15 drops of water to each tube, and shake each of the tubes to mix the contents. The insoluble salt that falls out of solution is known as the precipitate, hence the reaction's name. Further explanation: Solubility is the property of substance as a result of which it has a tendency to dissolve in other substances. EXAMPLE NaCl (aq) + Hg(NO 3) 2 (aq) NaNO 3 (aq) + HgCl 2 (s) 1.
