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.

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...
