#2 Post of Spring Semester!

Haha, when I logged on, my desktop was full of icons. LOL someone was bored...I had to delete them all. All 200 of them. o_o Ugh, I had a crazy week last week. o_o I don't feel like talking about it. bwaha. Okay, I shouldn't have mentioned it then. -__- Sorry, I had a long day.

Anyway, we're currently learning about solutions. In a lab that we conducted last week, we mixed solutions by dissolving a solid (cobalt chloride).
The expected absorbency was .24 and my group's mixture absorbed exactly that! We also made a solution by diluting a concentrated solution (potassium permanganate). The expected absorbency was this .18 and our groups was .17. :D Nice! By the way, we had to calculate to solve these labs. We used equations to determine variables such as molarity, volume, and moles of solute. Molarity = moles of solute divided by liter of solution. We also used labs to conduct the properties of solutions such as solubility, density, and how freezing temperatures of solutions vary. For example, ice water with salt has a lower freezing temperature than pure water itself. When pressure is high, gas is more soluble.
