LOOK AT THE PRETTY CHEMICALS
iodometric determination of vitamin C
in chemistry today my teacher showed a comparison of coronavirus cases to the election map of america (if i daresay, iconic of him) and bearing in mind we're a.) in a chem lesson b.) it's a given we know basic geography because it's a levels
someone pointed at florida and asked if it's italy.
and i tell you my poor teacher looked more disappointed than when i fucked up my titrations

3•31•17 - 8:27 pm // Reviewing for my third chemistry midterm tomorrow morning ft. my rose globe lights💡🌹

Took a nap today so I’m wide awake right now. So I decided to start next week’s lab a little early by annotating the procedure. WHICH IS A GOOD THING TO DO WHEN YOU TAKE ANALYTICAL CHEM. Seriously. These labs always take the longest time to performed and knowing what to do makes it easier on you.
experiment 8 - determination of total salt in a mixture using ion exchange chromatography
the first image is a titration using phenolphthalein as the indicator, it’s just barely reached the endpoint and is a very pale pink! more pink irl I promise. 3 of these titrations were completed in order to standardize the concentration of NaOH which was used to titrate.
in the second image you can see the beautiful pink colour of the methyl red indicator we used in our titrations of sea water! this is before the end point, at the endpoint it turns yellow (you can see some earlier titrations in the background!).
