I’m curious whether any salt would at all dissolve in a liquid metal, such as gallium, mercury, or some other metal in the liquid phase? A Google search of “solubility of NaCl in Mercury” …

If I have a diprotic acid that is +1 positively charged in its fully protonated state, I can figure out the apparent equilibrium constants by titration with base. The net charge will be neutral after …

In the 1980s when software for drawing 2D chemical structures was in its infancy and most chemists didn’t have access to the workstations that could convert 2D to 3D structures, many labs had physical …

The given Z vs P curve for 1 mole of a gas at 400K starts at Z=1 & P=0. The slope at the point when the curve again intersect Z=1 is 0.005. The critical temperature of the gas is 500K. My approach:…

Currently studying how to “compute” term symbols. My book gives the example of carbon. Carbon has the electron configuration $(1s)^2(2s)^2(2p)^2$. We can ignore full orbitals, so we only …

I have read that A1g modes are identifiable in Raman spectra by looking at cross-polarised Raman spectra and seeing peaks that strongly reduce in intensity. So essentially, the intensity of A1g modes …

If E/Z is a type of stereoisomerism, then you should be able to use the formula $2^n,$ where $n$ is the number of stereogenic centres. How is it that there are 16 possible E/Z isomers according to the …

Greatest hits from previous weeks:

As part of a pre-lab exercise in Chemistry, we went through the necessary calculations to identify an unknown metal in a metal carbonate. The method was gas evolution by means of hydrochloric acid (…

How can we theoretically decide the acidic or basic nature of an oxide? What are the reasons/ factors which make an oxide acidic, basic, amphoteric or netural?
|

Is the melting and boiling point of ionic bond usually higher than covalent bond? I know that compounds with ionic bonds are usually solid at room temperature, so I want other answers than this. (…

I read my book and learned everything about enantiomers, racemization, $\mathrm{S_N1}$ and $\mathrm{S_N2}$ reactions, but when I’m trying to identify molecules as chiral or achiral, I get confused. …

After reading a number of explanations about it after googling, I’m a bit confused on this. Some explanations are doing it using a solution density, others aren’t, though most are. On one site it’s …

So I came across this diagram,the other day: As a chemistry student, I am well-versed with the dashed and wedged lines, but I was wondering what the wavy and the dotted line represent?

I’ve already searched online some information about this equation, but everywhere I read, there’s also sulfuric acid, which we did not use in the laboratory. We only used potassium permanganate and …

Can you answer these questions?

I bought some safety sunglasses and didn’t notice until I’d taken the tags off that there’s an annoying logo painted or printed right in my field of view. (You can feel with your fingertips or …

I am little confused about when it comes to assigning configuration of planarly chiral cyclophanes – and I think it comes down to selection of pilot atom. All sources I have came across say that the …

My question is similar to this one, however that question seems to ask about how it improves combustion in general, not specifically with respect to sugar rocket fuel. The answer to this question …
