In order for NaCl to be soluble, the Na + and Cl-ions must break free from the crystal-lattice structure of the solid. When the ions are in solution, they are surrounded by water molecules, and the ions are said to be solvated, or dissolved in an aqueous solution, denoted (aq).Hence, the process of dissolving a NaCl crystal can be described by the following chemical equation (Equation 1):
Pyrolysis is the thermal decomposition of materials at elevated temperatures in an inert atmosphere.
