Murder Investigation Molarity Lab

This lab was just stupendous. I found it much more enjoyable than other labs due to the fact that this lab came with a backstory and a mystery to figure out. It makes the experiment more engaging and intriguing since we have something extra to discover. We did a great job throughout the lab and felt pretty confident with our choice of the culprit for Mrs. Scarlet's death. We figured this out from calculating the molarity of an unknown fatal substance. I hope we have more labs like this in the future.

Identifying an Unknown Substance

First Lesson of the New Year

This lecture was fairly smooth. I feel like I had a pretty good understanding of the lesson. The lesson was titled "Using Molarities in Stoichiometric Calculations" and it began with a very helpful flow chart. A key point that really helped me was the concept of "want/have" or "what you want over what you have". That concept really helped me through the first example and simplified the lesson. After that we learned two new key terms: endpoint which is the moles of acid = moles of base, and titrate= acid base reaction.

First Lab of 2016

This lab was fairly easy. We picked our choice of food coloring as blue. Then we put that food coloring into a small cup and kept on extracting a sample of the previous solution and adding it with water. This caused the color to eventually disappear.
