Test

I feel that I did pretty well on this tests, Im not quite sure really. I felt like I knew all of it and I didn't guess on more than one, but you never can be sure with these tests. I was really hoping that wed have a snow day Thursday so I would have 5 days to study and prepare but I tried my best so theres nothing more that I could have done.

Molar Mass of an Unknown Acid

This lab was very similar to the vinegar lab. We began by titrating KPH again to standardize the base. Then we proceeded to dissolve some of this unknown solid acid in water then we had to heat it and stir it as it is rather insoluble. We then titrated it however this would turn pink and then it would change back to clear. In the end our results were very good as we got about 179 and the actual mass was close to 180. Later we were told it is none other than the acetylsalicylic acid that we had cooked up at the beginning of the year!

Vinegar Lab

In this lab we titrated a measured amount of KPH dissolved in water. This was done in order to standardize our base of NaOH and get its molarity. After this was done we then titrated some vinegar. It was very interesting seeing the solution change color and then change back. I enjoyed this lab greatly.

Quiz

So we found out the grade on our quiz today, I got a 66.6% which means I missed 1/3 of all of them which is.. unfortunate. I felt i got all the math problems right it was just a matter of me not getting the actual knowledge about acids and bases, I will update once I get my quiz back.

x = -b......

So we learned a new lesson today that involves, wait for it, the quadratic equation! You know that equation that you memorized for the one question in 8th grade, yeah.... The formula goes as follows
But yeah you use this during ICE box problems which they are not very fun, at all, I understand them however which is good. I need to study...

Absent

I was absent for the first lesson, I had some sort of allergic reaction which caused my eye to swell to the point that I was unable to open it. However I am better now so that is awesome, I missed our first lesson which was about conjugate acids and bases, I think I understand it, the acid gives an electron away and then becomes a conjugate base, and the base gains an electron and becomes a conjugate acid. Here's a few links I found helpful:
