One of the commonest ways of obtaining potassium carbonate is to leach it from the ashes of a wood fire. What does that tell you about how well it is absorbed by charcoal? While you could separate it from water by reverse osmosis, I think it's going to be easier to let the water evaporate.

In fairness, Nature didn't just take a stand against Trump. The whole of the Republican party seems riddled with anti-science. https://god.dailydot.com/moons-orbit-climate-change/?fbclid=IwAR2ty1F0BrUSa02Pk3JZjj5ARQheENsyjLSi41EMfVY9bYC-FUCXbmb4PK4

If people being near you was assault (and I doubt it is) then assault and battery (or worse) would not be a legally reasonable response anyway. Did you miss the thing? Let's just say I think this is a medical issue, but not a respiratory virus issue.

It is utterly impractical to consider getting K2O by heating the carbonate. It will not work. If you want KOH there are ways that do work. The same chemistry they discuss here https://pubs.acs.org/doi/pdf/10.1021/ie51398a020 is probably the easiest way.

Not to any meaningful extent. The decomposition temperature is very high and there's a lot of CO2 in a fire which drives the reaction in the "wrong" direction." The question does not arise. You can make potassium hydroxide from the carbonate by reaction with slaked lime

That's what I wondered about. What you seem to be doing is making a crude vinegar as a source of acid by leaching plant material and then "fermenting" it to glucose, then ethanol, then acetic acid. If you apply that directly to the soil, various bacteria will oxidise the acetic acid (to CO2) and you will essentially have added anything water soluble from the plant waste. That's likely to include essentially potash and will make the soil alkaline rather than acid. But I would have thought the cost of purifying the dilute acid was more than the cost of buying something like (NH4)2SO4

By the time Millikan was doing his experiment, the nature of the electron was sort of know. Thomson had characterised cathode rays as a stream of some sort of particle. It's plausible that Millikan was trying to characterise the particles better.

What do you think the word "glacial" means in this context?

The Raman effect is not reflection. That image is neither a reflection, nor a Raman image. It's not clear that you have enough understanding to ask good questions here. YT videos can be a great way to learn stuff, or they can be so "dumbed down" as to be useless. You probably need to expand your list of sources.

For those who aren't aware of it... https://en.wikipedia.org/wiki/CRC_Handbook_of_Chemistry_and_Physics But, not every possible reaction is in there. So, fundamentally, if you produce (or find) a new compound, you might be able to guess it's properties but generally, you will have to measure them.

Why not? The temperature dependence is usually quite strong; the pressure has less effect. Yes, but it won't help much because you need to know the energy change for the reaction. https://www.chem.purdue.edu/gchelp/howtosolveit/Thermodynamics/TemperatureDependanceOfK.html Pure HCl is a gas. The case of pure liquid acids like H2SO4 or HNO3 is complicated.

How do you know it wasn't simply that your immune system did its job? Dilute solutions of chlorine (prepared electrolytically or otherwise) are certainly antibacterial. So, nearly a million fold range of H+ concentration. Doesn't look like the sort of quality control I would like for a medical product.

Not where I am. In the EU there's a limit of 200 mg/ l for sodium in drinking water. That's about 8 mMol per liter If you electrolytically exchanged all of that for H+ ions you would get a pH of about 2.1, so a pH of 2.4 means you are close to the limit for good drinking water. My tap water has about a tenth of that much- corresponding to a pH of about 3.1 Is there any evidence that it works?

A matter of indifference to the agricultural community. How? Anyway, I'd avoid the use of hydrochloric acid; the chloride ion tends to build up in soil and "poison" the plants. If there was a "cheap" way to make, for example, sulphuric acid, then the people who make sulphuric acid would already be using it. So it's unlikely that you could make it much cheaper. I vaguely wonder what would happen if you mixed powdered pyrites into the soil. It might oxidise to sulphate (slowly) .An interesting experiment; but with no guarantee that it works or even that it's cheap.

And for zinc- which is often used in school experiments on photoionisation, the reflectance drops like a rock in the UV region https://tubingchina.com/HDG-Hot-Dip-Galvanized-Surface-Reflectivity.htm

Is not a common recipe

As an anti-caking agent in salt. It's not the only one used. That's why I also motioned MgCO3

How?

Air is a good enough oxidant. I can imagine either magnesium carbonate or sodium ferrocyanide acting as a catalyst.

I wouldn't like to have to rule out Cr(VI) as the cause of the yellow colour. How important is the beer?

The biggest problem with a jar full of electrons is that they repel eachother and stick to practically anything.

James Wimshurst would have laughed at you and installed a clockwork motor or a magnetic drive. I don't know about Wimshurst generators, but it is common for Van de Graaff generators to be run in pressure chambers. High pressure sulphur hexafluoride is used as an insulator. Unless your battery has something like ten thousand cells in series, that's a horribly inefficient set-up.

I'd imagine you are right. But part of the problem is that Trump isn't interested in asking what they like; he's interested in telling them what he likes (or, at least pretends to like) So, he's the one telling them that they can't get a decent job because of immigrants. He's the one telling them they need to have more guns to stop shootings. He's the one telling that that the democrats would poison puppies at perverted orgies ... or whatever. While, in fact, it's the Republicans who seem to get found to be misbehaving. But the media is run by billionaires. Most of the folk voting for Trump do not realise that they don't have much in common with a so called "rich" businessman.

Did you post a response?

Fascinating. Can they do the same with other viruses like HIV? Probably a discussion that would warrant another thread.
