Aqeuos Solutions Test Reflection

Well, I got a 63%. That is not what I would have liked, but I will not complain, as it is all reflective of my work and effort in chemistry class. I actually guessed a LOT of answers on this test, and did surprisingly better than most people... So many people failed that she has issued the option for a retake. I know I would not do better on a retake, though, so I am not going to gamble my passing grade. Phew.

Vitamin C Lab

Today in chem class, we tested the concentration of vitamin C in many different drinks that are suspected to have a high concentration of it, such as pear juice, grape juice, and others. We then used a starch and an indicator to titrate the drinks and when they turned blue, they were done. Going from the number of drops or ml that it took to titrate, we can figure out the concentration of vitamin C in each, based on a standard we made by dissolving a vitamin c tablet.

Aqueous Solutions

An aqueous solution, put simply, is when a compound is dissolved in water. We can measure the concentration of a solution in units of Mols/Liter. also known as its Molarity. The higher the molarity, the more concentrated it is, and when dealing with acids and bases that are strong, that means BAD news if you spill it on yourself. I will attach a few links below to some molarity resources.

Murder Investigation Lab

We have begun a "Murder Investigation Lab." Basically, we have been given a statement that says someone was murdered by a chemical and lists off the possible killers, victims, and their possible murder chemicals of choice. Based on the reaction that took place, we can calculate the molarity of the chemical used in the murder and match it to one of the possible murder chemicals. hopefully it wont be too hard.
