Is an acid-base reaction a redox reaction?

Is an acid-base reaction a redox reaction? And is redox reaction the general term for acid-base reaction?
Chemistry substance concentration?
ByKxrl11
Hello folks. We are currently doing chemical arithmetic in chemistry. I just watched a video about it, and there was talk about a substance concentration, so mol/liter But we never had that in class. Can someone explain this to me and how it differs from the molar volume of 22.4 liters/mol. And shouldn't there also…
Chemistry?
ByDiana776
In chemistry, we have to filter unfiltered coffee and label a sketch. Unfortunately, I can't find a sketch on Google that includes the required words. Terms: filtrate, filter, extract, extractant, suspension
Chemistry pH values of salt solutions?

Hello🙋♀️ I'm writing a chemistry paper on Thursday and I'm stuck. Why is the concentration of sodium acetate (NaAc=0.1 mol/l) the same as the concentration of acetate (Ac-)? Thank you🧪

Reaction of acid and alkali?
ByMetles
Hey everyone, to the chemists among you. Can acid and alkali be corrosive when mixed? By the way, can they cause a corrosive effect? I know that they basically neutralize each other and form a salt. But the reaction generates heat (it was assumed that this would cause a corrosive effect). Thanks in advance🙃
Even they are not really ‘stable’! There are also no real applications, or significant quantities! The ‘stability’ and quantities are just enough for proof!
The half-life of Oganesson is 0.89 ms. Detection can be achieved through the products of an alpha case! The quantity is not sufficient for further investigations.
> Even they are not really ‘stable’!
There is the assumption that in order numbers beyond the 160 there are again stable(re) elements.

Stable? No way.
In the Nineties there were speculations on stable, undetected natural elements on the earth, but they were dissolved in air. The most modern model calculations of atomic nuclei predict a significantly weaker “island of stability”, especially in 114, 120 and 126. We’re talking about seconds instead of milliseconds or microseconds.
For elements beyond the 118 there are neither suitable synthesis routes nor technical installations.
The hardest elements with which aqueous chemistry can be operated are fermium and mendelevium.
Hmm, isn’t my specialty, but what should devices and ways of the next elements differ from the last 6 elements? Mergers are produced in particle accelerators and hopes that something new and detectable is created!?
Only now are the quantities, rather number of manufactured isotopes and half-life soo tiny that you need more and more experiments to find something!
‘spanning’ is also in that the next element is in the 8th. Period would stand! However, it is naturally chemically and spectroscopically irrelevant, since one could never operate chemistry with it and therefore the orbitals of the 8th. Shawl cannot really be investigated!
I can’t judge whether you’ve been counting ‘stable’ elements on each side of uranium. But you might tend to be ‘threat’ if you find something and can prove it at all!
Yield and beam density are not sufficiently high today (“barn”). Each previous element was already the limit of the technically possible. And then the detection must take place in the μs range. Dubna’s coming up. As it looks in Darmstadt and Berkeley, it remains to be seen. A lot of research money and benefits are more likely not to be fetched with new elements.
It’s not like you haven’t tried to make all the elements up to 127! Only most reactions are too “hot”, have too small a cross section or simply do not work.
The following video about Victor Ninow and fake data is quite worth seeing:

I would also like to see a chemistry of (stable?) Viewing elements 120 and 126, it closes realistically but out.
It’s not that easy again. The detectors cannot exceed a specific beam density. Secondly, the reactions must be as asymmetrical as possible in order to succeed. Meaning, milligram Berkelium or Californium is required. Thirdly, the neutron-rich isotopes eventually go out.
Thx for the info…
Sounds for me in the end only after ‘more of it’ (larger, more energy and performance) and not after ‘complete new ways’…
What we can do here on Earth with particle accelerators is easily surpassed by colliding neutron stars. If there were stable cores beyond the order number 118, you could find a few.
Nobody knows. Didn’t Sheldon Cooper find one?
Is there any theories about it?
