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

Re: Calcium Hydroxycitrate vs Hydroxycitric Acid + Alpha Lipoic Acid

Yes of course it will work. But you have to know which one you will make. Citric acid has 3 Protons, these can be exchanged step by step by a metal, here Calcium, which is bivalent. So there will be CaHCit., Ca(H2Cit)2 and Ca3(Cit)2.

Re: Calcium Hydroxycitrate vs Hydroxycitric Acid + Alpha Lipoic Acid

We can not give answers for pharmaceutical purpose.

(Hydroxy)-citric acid can be neutralized with Calcium carbonate to the citrate.
