I am the nature hacker and this is your world so right now I'm bubbling bubbling co2 into sodium hydroxide liquid so if you check the description below I'll give you the recipe but it's basically just distilled water with enough potassium hydroxide in it to saturate the solution until no more potassium hydroxide would dissolve and if you have too much potassium hydroxide it's okay wait wait I'm just keep bubbling co2 through there and you can see it's getting cloudy now and that is a bunch of potassium hydroxide linking up with the co2 forming potassium bicarbonate and now if you watch the the bubbles shrink so that's a good sign that the co2 is being sucked up by the hydroxide so here you'll also be able to see the bubbles shrink it's happening less than it was before because the solution starting to get well the hydroxides leaving and it's forming into carbonate so yeah it was in an ice bath which is important so now you can see the bicarbonate just collecting on the bottom of the jar there so it took it took probably about an hour for that to happen so pretty much there I'm going to call it and there's the bicarbonate on the bottom of the jar and now I'm going to pour off that top solution into this bottle and that's a there's still a lot of potassium hydroxide in there so I'm going to recycle this I'm going to use this and then just add a little more potassium hydroxide next time before doing again so we're definitely conserving I'm trying to pour off the liquid without getting too much of the bicarbonate in there so what we're doing here is just conserving as much as possible we're not throwing away the excess unreacted unreacted potassium hydroxide we're going to use that again next time so once this is fully poured off here what I'm going to do is I'm going to wash it with a bunch of ethanol that's right ethanol 190-proof Everclear which I'll show you in a little bit and so because alcohol can dissolve the test my drug site but it cannot dissolve potassium bicarbonate so there's my liquid I'm going to recycle and I'm going to use that next time and so there's my potassium bicarbonate there now we need to get all the excess potassium hydroxide out of there so I'm going to use alcohol to wash it many many times I probably washed it like this and then stirred it I probably did that 10 times at least trying to get all of that potassium hydroxide excess to dissolve into the ethanol and then I collected that ethanol so I'm not even wasting the ethanol and I can just dissolve I can just distill that ethanol and it will leave the potassium hydroxide behind and I will collect the alcohol back so adding more ethanol and stirring and then pouring that out and then adding more pouring it out just washing there collected all of it that's all the ethanol and there's all the the water from the beginning there so collecting all the waste and we can reuse that we can reuse that waste so nothing is wasted the ethanol can be distilled and the ethanol can be any collective and as far as just that water solution I poured off at the beginning that can be used as the base for next time I'll just dissolve more potassium hydroxide into that liquid next time and then rebuttal and more co2 and the co2 you can buy from a brew your own brew store like a home brewing store you can buy a tank of co2 for pretty cheap I mean it costs like something like 70 bucks but then you can keep getting it refilled for only like 5 20 bucks each refill so so yeah that's pretty much it that's how to make potassium bicarbonate you could also do the same thing with sodium hydroxide to make sodium bicarbonate which is baking soda but thanks for watching I am the nature hacker you were
