And potassium hydrogen tartrate is about ten times less soluble. (0.57 g/100 ml (20 °C)) So, we both agree 66% is very soluble. We both agree that 0.57% is a low solubility. So you should realise that when I am talking about something with a low solubility, I'm talking about potassium hydrogen tartrate rather than potassium sodium tartrate. Especially when I explicitly say so. I'm not certain what you mean by "" But the forum labels me as such; it wasn't ever a secret. And you guessed that I meant potassium sodium tartrate even though I said potassium hydrogen tartrate. And you did it even though I made the point that it's not very soluble, so I couldn't possibly have meant potassium sodium tartrate. Also, Re. Guess again. Plenty of reactions with water are violent, e.g. https://en.wikipedia.org/wiki/Bhopal_disaster

Would you like another guess? https://en.wikipedia.org/wiki/Potassium_bitartrate#History If a chemistry expert tells you something has a low solubility, then they are unlikely to be talking about something that's very soluble.

One possible problem you will face is that potassium hydrogen tartrate isn't very soluble. Another is that the process of dissolving sodium hydroxide in water can be violent, even without acids present. And your KOH is probably only about 85% pure- the rest is mainly water.

The rochelle salt lattice only really works with equal numbers of both cations (you can substitute some NH4 or Rb in place of K if you like).

Get well soon. It's the latent heat of evaporation.

You can do chemistry this way but it is horribly inefficient. It's difficult to maker perbromates (and amusing to look at old books "explaining" why they are impossible) One way to do it was to make a selenate with the right isotope of selenium, and wait for it to decay. https://en.wikipedia.org/wiki/Perbromate#Synthesis

It's a bit like that thing where they put lots of effort into eliminating smallpox. Total waste of time because you just don't see it anymore.

Is inflation what happens when people start to realise that money is intrinsically worthless?

It's the actual density of silver What does that mean? Is it something your model does? Do you realise that your model does not affect the density or composition of a piece of metal? How can it identify pure silver? It can't distinguish it from a silver/ copper/ gold alloy with the same density, and there are essentially an infinite series of those.

Are you deliberately missing the point? The actual density of silver is 10.49 You can invent any alloy you like with that density, and I will tell you that you have got it wrong because the real alloy it has more silver (Or less) than you suggest. Changing the silver content does not ( to a first order approximation) change the density at all. If you choose to be a bit more precise then adding silver changes the density slightly. But you can always get it back to exactly 10.49 by adding either copper or gold. So, whatever composition you suggest, I can say you are wrong. Your method simply can not work.

How do you know it isn't a 50:50 mixture of that alloy and pure silver (which has a density of 10.49)?

JaiHind15 Never mind all that tripe. I have a piece of metal with a density of 10.49 exactly. It's made from all 3 metals Ag, Au, Cu What is its composition? If you don't know, just say so.

The device rejoices in the name of an earth inductor. https://geomag.nrcan.gc.ca/lab/vm/inductor-en.php

Then your study is wrong, for the reason I gave earlier.

In the particular case of the CuAuAg system, I think the colour would give you a hint. If you measured the reflectance spectrum carefully, it would probably be sufficient. The electrical conductivity might also work, or the hardness, or the speed of sound, or the melting point or magnetic susceptibility or the electrode potential or melting point. But the point remains; you need something to tell you where on that line you are. If you are in the UK and there's a point on the line corresponding to 9 (or 18) carat gold then that's a fair bet, but no proof. But in the USA they seem to prefer 10 carat (as far as I can tell).
