Hydrochloric acid state standard specification 857 - 95 synthetic technical brand A.
Transparent colorless or yellowish liquid (brand B — 1 grade: transparent yellow liquid). Hydrochloric acid — caustic, stable in the chemical relation, incompressible fluid. Dissolves the majority of metals and their oxides, in it glass, ceramics, porcelain, graphite, ftoroplast are steady. Smokes in air, mixes up with water, benzene and ether.
Now hydrochloric acid has wide range of application. In particular it is used:

at clarification of metallic surface for soldering and tinning;
when receiving chlorides of different metals;
when cleaning products from ceramics and metal from dirt and microbes;
by production of food additive E507 in the food industry.
If hydrochloric acid is technical, then it is widely used in medicine, the chemical and food industries, at the enterprises of ferrous and nonferrous metallurgy.
