I'm ready to see some magic.
Hi, I'm Lewis. I'm on the Steps into Science level five course.
We're doing the effect of temperature change on reaction rate.
We're adding five centimeters cubed of sulfuric acid. Now we're adding two centimeters cubed of potassium permanganate and 40 centimeters cubed of water.
We're going to be lighting the Bunsen burner. We have to make sure that the hole is closed on it so that we don't get a blue flame.
We're currently heating this to about 40 degrees. Once that's at 40 degrees, we can take it off and add our oxalic acid. Once we've stirred it, it should turn colourless. That's when we can kind of judge the rate of reaction.
Chemistry is the best.
Now that we've heated this to 40 degrees, we're just moving this onto here so we can add our carboxylic acid.
Oh, here we go. So from that we can understand that it takes 1 minute and 18 for its turn colourless, which at 40 degrees is the rate of reaction.
So now we're going to repeat at 50, 60 and 70 degrees.
While we're waiting, what is the best Taylor Swift song been?
Right. I think we can cut the video later. 55 seconds. So at 50 degrees, it's a lot faster at 55 seconds.
60. Oh that was way faster third one done 17 seconds at 60 degrees this shows that as the temperature rises the rate of reaction speeds up I really see some magic
This is taking forever. 7.91 seconds. 70 degrees. It's the fastest of all. It's 7.91 seconds, which again just proves as the temperature goes up, so does the rate of reaction.
This has been a science experiment brought to you by me.
