Before bottled gas was delivered, chemists would make their carbon dioxide with a Kipp’s Apparatus.
Dr Samantha Tang (with Neil, of course) dusted off the one stored on Professor Poliakoff’s window sill.

A.I. Experiments: Making it easier for anyone to explore A.I.
I thought this co2 was invisible anyway? i presume the gas was the same regardless what medium it went into
The chemical bond between cupper and the sulfate is stronger then cupper with carbonate so norhing happens when you lead CO2 through it. Carbonate bond is stronger then hydroxide so it replaced OH by CO3 in the limewater.
Yet again, another excellent video which left me with a smile on my face. As always, I have learnt something new and interesting.
Still used at Universidad de Concepción for biochem and chemistry students. Funny enough, the career takes 6 years because we take 13 courses of chemistry and a lot of biochem and clynical chemistry with the necessary enzyme knowlesge of course.
"How to make Carbon Dioxide (The Old-Fashioned Way)"
Takes a deep breath, exhales
Experiment over
Breathe lol
How to make OXYGEN (in an easy, cheaper and also safest way) in an unventilated room.
If you react CO2 with say Copper nitrate you will generate HNO3 which will react with CuCO3 to give Copper nitrate again so no precipitate.
Barley wort, water, sugar and yeast produces the best results for me. the end result is always very satisfying.
This is such a cool apparatus! I would use this all the time.. Lol. However, it seems like you need a lot of HCl before it fills up enough to reach the CCaO3 in the middle bulb, so when youre done, theres a lot of HCl that gets wasted. Maybe this could be resolved by just filling up the bottom bulb with a bunch of solid material that wouldn't react with the HCl (glass, steel bearings, etc), but merely take up enough volume to help the HCl get up to the CCaO3 in reasonable quantities.
Breathing maybe?
Does Neil ever speak on video?
Usually if you want to make carbon dioxide you need the blow hard,s in the senate and congress open a session on global warming . Then when it's done let them fly private jets to their favorite vacation spots !
carbon monoxide. please ?
Here in the US, they sell little prank stink bombs that pop just like your Bomb bag packet, except they make the room smell like flatus
ALMOST a perfect loop of "Free Energy"
Well kids, what have we learned today? Be humble, as Professor Poliakoffs, and think by yourself instead of blindly believe in what your adviser says to you. As humans, we all commit mistakes, even our most admired Professors. 🙂
in my opinion sulphur dioxide was generated by the reaction of HCl and CaCO3 – moistened litmus paper would have clearly turned red and not yellow indicating the presence of a stronger acid within the 'gas' than what one would find in CO2 with litmus paper turning yellow! Also precipitation didn't occur in my opinion because both the copper sulphate and lead nitrate are salts (unsure about middle test tube) whereas limewater is not a salt and was able to allow the salt within the SO2 to precipitate!
Used to love Kipps apparatus. We had one at school and also in the first laboratory I worked in a histology lab. Also had them in several schools I worked in later, we also used one for generating hydrogen sulphide.
now do bongs
Smarter everyday thats cool…i use 2 love those bag toys wen i was a kid
So could you use this but put Ammonium Nitrate and Sodium Hydroxide in instead and get ammonia gas out, which one could then cool, dry, and condense into pure Ammonia liquid?
Really didn't know why co2 couldn't replace so4 or no3. Lost all faith in this channel
I'd like to own an apparatus like that. Old school.
You could use "fenalfetaleina" (don't know the name of this compound in english) to show the pH change caused by CO2 going throught water!
That Kipp's apparatus looks like it's made from uranium glass. Have you ever shined a UV light on that bad boy?
Ingenious.
excuse my ignorance, but where is the video about extracting CO2 from Air.?
Finally, something I can do at home!
0:05 I have been wanting to do what that guy is doing for years.
Now I'm really jealous.
OMG the professor was wrong!! HOW?!!
That was Destin??!!
This video is satisfying anyway
How to make carbon dioxide. Breathe in, breathe out. Done.
Is this how CO2 is collected for commercial use?
