The hand-held fire extinguisher is simply a pressure vessel from which is expelled a material (or agent) to put out a fire. The agent acts upon the chemistry of the fire by removing one or more of the three elements necessary to maintain fire—commonly referred to as the fire triangle. The three sides of the fire triangle are fuel, heat, and oxygen.

Class Notes for Environmental Geochemistry. To do this problem you simply calculate the activity of Al 3+ in equilibrium with gibbsite at each pH value and then use the the equilibrium reactions linking Al(OH) n 3-n with Al 3+ to calculate the activities of each Al(OH) n 3-n species. The sum of all the molalities of all these Al species would be the solubility of gibbsite at each pH point.
