Re: Colloidal gold
Some reduced products of the citrate.
Mainly aconitic acid and Isocrotonic acid salts

Re: Colloidal gold
Yes gold will be oxidised to Au 3+ by chloride
The citrate is reducer back to gold.
There several methods in the net.

Re: Colloidal gold
To less information. Where does the Gold comes from. With salt, citrate and corn syrub you cannot make Gold.
Which movie do you refer to.

Re: PhD application
I would ask the universities requirement. But degrees mostly not so important to get things done. Later in a job nobody ask for it.

Re: HCl Concentration
HCl is a gas. The acid is a solution of this gas. With boiling is not possible. The gas has to be pressure into the solution.
But did read what I said before. NaCl acetic acid will not react. You have still a mixture of salt and vinegar.

Re: HCl Concentration
It will not work.
HCl is a strong acid and acetic acid is a weak acid. You can only make acetic acid by treatment of sodiumacetate with HCl, but not backward.

Re: How to destroy fiberglass rephrased
Fiberglass is a compound of glasfibres with epoxy resin. These are very difficult to destroy. The resin can be attacked by some solvent like alkylglycol ethers, NMP, DMF, Tetraetch and others at alkaline conditions at high temperature followed with an alcaline Permanganate etch. The glass can only a...

Re: Bond angles and hybridizations at atom in the molecule of aniline and other unknown molecule
I would say Fluorine ethyne acetic acid ester.
Aniline is correct.
