Ammonia Fountain Mel Chemistry

Ammonia Fountain Mel Chemistry Using the same trick, pour out all the ammonia chloride nh 4 cl from the bottle (1 g) into the same test tube. insert the test tube into a beaker. add 0.5 ml of water into the test tube. cover the test tube with a flask to collect the releasing gas. wait for about 5 min., until the mixture stops bubbling. Sprin­kle sodi­um hy­drox­ide into the con­ic flask and add the am­mo­nia so­lu­tion. col­lect the am­mo­nia that forms in the round bot­tomed flask, turn­ing it up­side down. seal with the cork with the glass pipe. keep the flask up­side down. in the crys­tal­liz­er with wa­ter, add drops of the thy­molph­thalein so­lu.

The ammonia fountain is a classic demonstration in which students observe the very high solubility in water of ammonia and identify that ammonia solution is alkaline. the teacher fills a flask, fitted with a glass jet, with dry ammonia, before injecting water into the flask. this dissolves the ammonia and causes a fountain via the jet. The first few drops of water that enter the upper flask absorb a little ammonia gas. when this occurs, a slight vacuum that forms sucks a little more water into the flask to balance the pressure. this water, in turn, absorbs a little more ammonia. this continuous exchange creates a chain reaction that causes the solution to come rushing into. In this issue: the ammonia fountain. the ammonia fountain is a classic experiment used to demonstrate the solubility of ammonia in cold water and the alkaline nature of the ammonia solution formed. the following method is a variation of the norm in which i initiate the reaction using body heat instead of water. source: adrian guy.
