Sagot :

Answer:

Water is an excellent solvent because it forms very strong bonds (covalent). ... However, not all substances will dissolve in water. Salts will dissolve, the covalent bond of water "rips" the ionic bonds of the salts. Sand will not dissolve in water because the "bond" of water is not strong enough to dissolve the sand.
