Vitamin C Pre-Lab Review

I decided to be partner A for the lab so that I would end up with the math portion even though I was't a 100% sure of what kind of math we were doing. I ended up not having any problems with the math but for some reason other people had problems with the math. So I want to explain how I worked through the problem. I saw that for both test liquids that it was 20 drops so I knew on that they both had the same amount. I also saw that they had different number of drops to change the solutions color and this was based of the concentration amount of the solution. Because of this it was obvious to measure the concentration with the drops needed then to use this known ratio to then find the number of drops needed for the other solution which we know the concentration of.

Murder Investigation Lab

The idea of this lab was quite simple. There were suspects and each had access to 2 different chemicals. However each person then had specific access to a distinct range of a molarity of that chemical. Using this we had to do a lab to first discover which chemical it was. If it was Silver Nitrate or Potassium Iodide. After this is discovered then once you find the molarity of that chemical then you can easily find your culprit.

Using Molarity in Stoich Equations

The mixing of Molarity and Stoich wasn't that big of an idea to comprehend. It ended up being quite normal and familiar to what we normally do. The equations looked pretty familiar to what we've done before. Pretty much we were converting Liters to moles and then just using that molar quantity in our stoich equation.

Molarity

I ended up missing the day in school when we learned this in class so for me it took a little to understand. I ended up just watching a youtube video and that helped a lot! The link to that video is here. I hope this video can help you if you don't already understand molarity because it sure helped me, and now I don't have any doubts on my ability to understand molarity.

Dilution Lab

The Dilution lab was EXTREMELY easy, and needed no real preparations. It was nice however to visually see the idea of dilution in action, You could easily see in each cup the color clearly becomes more clear in each cup even to the point that there was no trace of the color in the first place.
