Conductivity Lab

In this conductivity lab, we used many different types of solutions such as . After following the procedures for this lab Leigh and I learned that if there are more ions in a specific solution than the conductivity level is likely to increase. 

As you can see from the results up above in the solution of lactase hydrate and distilled water, the number of ions were at such a limited rate that the intensity was rated a 0 due to the fact that there was no visible reaction. However, when we looked at the mixture of calcium sulphate and distilled water, along with potassium chloride and distilled water they both showed outstanding conductivity. The ions that these two substances portrayed were clearly visible to the naked eye and resulted in a high conductivity level. Although the substances I have already discussed either had a high or very little conductivity level due to the ions, there are those that were simply mediocre or ranked a medium ion conductivity level. These substances included calcium sulphate and the corn starch mixture. The conductivity level in these substances were just average. There was not much to them, but still enough to be existent. Overall, conductivity levels vary depending on each substance or mixture being tested for the conductivity of ions.

Test Reflection

Who could have guessed that studying actually really helps when it comes to test time!!! This past test we took regarding the elements of the periodic table was one that I studied exceptionally hard for. My previous test I only received a 60% and it really upset me. I was not prepared for that test, and I was determined to be ready for this one. Since the first day that Mr. Ludwig informed us about this test taking place that friday I began taking the practice test over and over. I soon realized that by doing the test over and over i began memorizing and learning more about the topic in which I actually understood what I was reading. In the end i began getting closer to a hundred on my practice tests until eventually I got 100% on my practice test multiple times in a row. Thats when I knew I was ready! Friday came and I definitely was nervous after all I nearly failed my last test and I didn't want that same thing to happen this time! So I took a deep breath and pressed start and let my smarts do the talking! I breezed through this test with ease as I realized my memory was not going to let me down. I knew the answers and there was no way I wasn't going to do great! Making my way through the test I came to the end where the finish button was calling my name. Nervously I pushed the button and found that I got 100% on my periodic test! So overall, I came to the realization that to do well in this chemistry class you have to study and take the time to learn the material!
