What non-toxic non-corrosive liquids are used for heat transfer?
You can use a heat transfer oil like Mobiltherm 610. They also have some other oils that you can use, if you are able to shield the surface of the oil from the air. If you use a lower grade oil, it ...

What non-toxic non-corrosive liquids are used for heat transfer?
A good starting suggestion is probably a mineral oil. These are often used in small scale labs for heating baths that need to reach temperatures much higher than boiling water. So they should be ...

What non-toxic non-corrosive liquids are used for heat transfer?
Mineral oil should be good (aka white oil). Vary similar to motor oil , flashpoints not easy to find but around 450 F. Or, for a much higher flash point- phosphate ester. I don't know what it is but ...

What non-toxic non-corrosive liquids are used for heat transfer?
This seems a very bad idea to me. Please tell us how you intend to heat the outer tank and some idea of actual dimensions; then consult a professional chemical engineer with experience in heating. ...

Why do we define molar conductivity?
Molar conductivity reflects ion or ionic compound behaviour, while conductivity reflects rather their concentration. For high dilution, the former is nearly constant, the latter nearly proportional to ...

Electrical conductivity of a NaOH solution
For posterity: it was a bad/expired batch of NaOH.
Got a fresh supply from a reputable supplier and works correctly!

Electrical conductivity of a NaOH solution
Note that DVM is Digital Voltmeter.
It may use too low DC voltage, what is OK for linear electronic components, but completely misleading for electrochemistry scenarios.
It may show high resistance ...

Conductometric titration curve plotting
Expressed in $\pu{\Omega ^{-1} cm^2 mol^{-1}}$, the ionic conductance of usual ions like $\ce{Na+, K+, Ca^{2+}, Cl-, SO4^{2-}}$ are between $50$ and $80$. But the two ions $\ce{H+}$ and $\ce{OH-}$ ...
