Solubility Experiment

Often when people are sick they will take as many drug as they want to relieve their symptoms, but they never know the side effect of taking too much drug. So it is important to know the characteristic of the drug and the amount that we should take.

 

In our chemistry class, we investigated the solubility and acidity of over-the-counter medicine: aspirin, Tylenol, Alka-seltzer, and tums—in different solvents.

A drug has to be soluble in order for the body tissues to easily absorb it. Our body should be able to absorb the medication easily for it to be effective. In addition, when drugs are not soluble, it is possible that there’s a residue of that drug in our body, causing adverse effects to our body. I think that is why we usually take medication along with water or any liquid and also liquid medicine since more of those drugs are soluble with that solvent.

Flame Lab

Every element on this earth are made out of atoms!

We all know that the best way to start a chemistry course is by learning about atoms structure and the element in the periodic table. In my chemistry class this round we did this one cool lab called the Flame Test, in the purpose of understanding how the electron (s) of an element reacts to heat.

We measured the result of the electron reaction through observing the color of the element when it’s in contact with flame. The reason that we see the colors is that of the energy that emitted by each electron when they excited corresponding to a wavelength of a the light.

One of the challenges that my team faced was that some pieces of the element dropped onto the bunsen burner tip so we had to make sure that it clean at all cost when we tested another element. Another challenge that we have is to observe the right color and note it down the right color. Furthermore, when we tested same element such as potassium but, we didn’t see the color change of the flame, so we just assume that the electrons gave out orange, which it isn’t accurate at all. Lastly, we have a lot of fun during this class and in the lab particular.
