Hiiiii guys! Alright so if you were sick today (Colleen) you missed out on another wonderful lab. The point of this lab was to figure out the different factors that affect reaction rates. Sadly, this lab was incredibly long and we did not have time to finish it today, but my group did make it through part one..or A, whatever you want to call it.
This part of the lab was testing the effect of temperature on reaction rates, and the reaction we were observing was between the slimy blue solution and oxygen. When the solution reacts with oxygen, it turns clear, when it is not reacting with oxygen it is blue.
By shaking the solution in the pipette, we were re-oxidizing the solution and caused the methylene blue color to appear. Once the solution was put to rest, it settled and the glucose in it reduced and it became clear again. This reaction time was measured at four different temperatures (in degrees Celsius ) : 10, 20, 30, and 40. My group's data looked like this:
Using this, we concluded that as temperature increased, the rate of reaction increased as well (which you might notice is the CLAIM part of your conclusion, you're welcome.) So, that was basically what we did today, we are going to finish the second part of the lab tomorrow. And the lucky person who gets to write about that is......Brandon L! Have fun Brando!
