About this app
This simulation recreates the environment of a chemistry laboratory in which there is a flask containing copper sulfate, a flask with sodium hydroxide, a flask with hydrochloric acid, a flask with ammonia, two test tubes, a rack, and three pipettors. The goal of the practice is to replicate the formation and dissolution of copper hydroxide scale formed in pipes. Determine the solubility constant of the scale and the amount of acid and ammonia that would be needed to dissolve the hydroxide formed.
