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: Combustion reaction of the alkaloid matemone C10H10NO3Br

What a big deal

4 C10H10BrNO3 + 47 O2 => 40 CO2+ 4 HBr+ 4 NO2+ 18 H2O

Re: Solution Chloroplatinic acid?

Sorry it is nonsense what you say. Even Chloroplatinic acid is used as an catalyst it is inorganic and not organic. If you don't know the difference then your expertise is poor.

By the way we dont like comercial Postings.

Re: Solution Chloroplatinic acid?

Convert mM in mg/l, use m = n* M
The density is not necessary, because its a solid material. You can only dissolve a powder in water. No volume.
Then calculate it for 10 ml.

Re: its right or not ?

Its ok , but there are no half molecules even mathematicaly correct

Times two

2 C2H6 + 7 O2 => 4 CO2 + 6 H2O
