AMMONIA GAS FOUNTAIN<br />
(3 of 3)<br />
Water Injected Into Flask Filled With NH3 Gas.<br />
The extreme solubility of ammonia gas creates a pressure drop which drives the water/indicator solution (clear)  in  beaker  into the flask by atmospheric pressure, creating a fountain effect & turning magenta with the formation of OH- ions
