Extracting the citric acid from lemons

A buffering solution is a solution that resists pH change. It is useful in synthesis when you need to keep the pH relatively constant during a reaction.
In my Cadaverine video, I used citric acid to make a pH buffer solution: • Making cadaverine

when life gives you lemons, extract citric acid.
-
I love how formal he is about juicing lemons
-
the urge not to drink the whole thing must have been overwhelming. Thanks for staying strong nigel

idk why but he reminds me of Bob Ross, the chemist version lol 'If the ph is a little higher than 9 that's ok', 'I'm not sure how much I added', 'will make a nice orange color'

Next Video: I extract iron from the blood of my enemies. Wow I never thought I would see so many likes on this comment.

For a purer product, it probably would be a good idea to re boil the calcium citrate in fresh distilled water after filtering, washing and drying in the frit, then filtering again after a short boil. This should really clean the calcium citrate for the reacidification step.

I've used citric acid before as a metal chelator in reactions which are sensitive to the presence of said ions, or in reactions where something might oxidise. I've used citric acid to chelate iron ions in solution when synthesising potassium salicylate (I was attempting to synthesise a soluble salicylate salt) as well as to slow the oxidation of salicylate in the presence of light.

My science teacher showed us this video in class but I had already seen it, so I watched it again, in class and enjoyed it even more.

I can sleep to his videos all day, and watch them all day too. His voice is soothing and he explains things very well. It's nice to hear before I fall asleep and in the morning waking back up to another of his videos. These are super well done, very educational, and entertaining, but also can put me to sleep because it's just such a soothing thing to hear! I dunno why I'm like this- HELP-

“Citric acid is present in many fruits but has the highest concentration in citrus fruits” mm yes, this floor seems to be made of floor
-
"A glass stir rod is added to the beaker." Like its an ingredient lol.

My dad heard me listening to this and asked what drugs im trying to make...
-
We had an assignment last week based on industrial and microbial production of Citric Acid. Nice to see it in practical too
-
I love this! I can't use most store bought citric acid because it's usually made from corn which I have a major allergy to, so now I can finally make all the bath bombs and food and beauty products my little heart desires!
-
ok but, how about extracting potassium from Bananas?
-
I wish this guy would be my chemistry teacher

In the Philippines we have a smaller and a lot more sour version of lemon, called calamansi which would make lemons sweet in comparison.
