Consider how easily halite (NaCl) dissolves in water. Why does quartz not dissolve readily in water?
What will be an ideal response?
Halite dissolves relatively easily because it forms from ionic bonds of elements that only have a charge value of one. Weak attraction results from lopsided distribution of electrons; positive ends of the water molecule (H+) are attracted to and dislodge the anions (Cl-) and the negative ends of the water molecule (O-) are attracted to and dislodge the cations (Na+). Water keeps the ions separated. In contrast, bonds in quartz are mostly covalent.
