Chemistry Demonstration Class

This week and last week we've been taught by our teacher Mr. Popoff, all about crystallization, saturated solutions, unsaturated solutions,Henry law and many more i’ll soon be defining and describing. Last week we were asked to bring a Coca Cola® can to class, we were not told why, we were just asked to bring them.  This Monday we had our Chemistry class, the class was basically like a demonstration on what crystallization really is, crystallization is the formation of solid crystals precipitating from a solution,melt or more rarely deposited directly from a gas. In our latest chemistry class we had Laboratory project that taught us how to make crystallization happen with destilated water and ammonium chloride, basically this was done in a test tube with certain amount of ammonium chloride, destilated water in it, heat bathed on a beaker full of water.

We also were explained on what a solution equilibrium is, which is when the concentration of the solute is the same throughout a system. We also were demonstrated physically what a saturated and an unsaturated  solution looks like; Saturated solution are solutions which the maximum amount of solvent have been dissolved. Any more solute added will sit as crystals on the bottom of the test tube or container, and unsaturated solution are solutions in which the solute concentration is lower than its equilibrium solubility. We were also cleverly explained what a Super saturated solution is, its basically a solution where there are more particles or solutes than solvent in a solution.

The coke experiment was actually really cool. We had about seven or less coke cans, ones were room temperature and ones were icy cold, we were trying to see which one of those based on their temperature, would burst more, it turned out to be the icy cold cans.
