What will dissolve brass

If either are mixed with sulfuric acid you will be producing some pure chlorine gas and we will be potentially losing several of our beloved Home Shop Machinist BBS members due to chlorine gas poisoning. People are poisoned or die every year from mixing drain cleaners and acids. I've seen some "Questionable" advice offered on this website and many others about different topics concerning such things as electrical wireing, welding tank storage, and other topics that if followed, have the the potential of getting someone injured.

There is a wealth of good advice available on this website, and I'm sure everyones intentions are good, but if there is any doubt about safety, check with an expert. Just my two cents. Good day. Err,Sulfuric Sulphuric in the mother country does dissolve Copper.

The Zinc is reduced to Zinc Sulfate Sulphate. Regards Ian. The trumpet shop where I work uses a chemical bath that is largely sulfuric acid granted, we add some mystery powder If we break off a tap or steel screw on a brass part, we dump whatever it is in the strip tank for a few days till the offending steel is gone.

The brass seems none the worse for the experience. Hello HSM members, 1st time here. I've read a lot of very helpful tips on this site. Thanks for being here and sharing. Quote:J Harp Gave it two hours in the battery acid, no luck. If used straight from the battery, it will be severely diluted.

I'm not saying it will eat brass, just that battery acid must be distilled to get any good strength sulfuric acid. All rights reserved. Yes No. Does acid eat brass? Oxidation is a natural process that dulls brass over time. Hydrochloric acid can restore your brass. As brass ages, it becomes oxidized and loses its shine. The acid eats away at the outer dull layer, exposing a fresh, bright layer underneath.

Nitric acid dissolves most metals including iron, copper, and silver, with generally the liberation of lower oxides of nitrogen rather than hydrogen. It can also dissolve the noble metals with the addition of hydrochloric acid. Oxidizing materials, such as nitric acid and dichromates, and complexing agents, such as ammonia and cyanides, are absent.

It can be used when redox reactions are being introduced or later on when students are trying to predict reaction products. Aqua regia is a mixture of nitric and hydrochloric acids.

It takes its name from its ability to dissolve gold, which is sometimes referred to as the royal metal. Only the acid solution of aqua regia can dissolve the higher karats of gold the third equation. Not really if it is from lead acid batteries but dont touch anywhere sensitive on the body just in case it has acid residue in it most of what the build up is caused by is electrolysis between different metals that make up the terminals brass or aluminium or plated copper and lead for the battery post oxygen also.

Brass is an alloy of copper and zinc. C The alloy will dissolve completely in dilute hydrochloric acid. The hydrogen ions react with the metal to produce hydrogen gas, which bubbles to the top of the solution and dissipates. These acids are capable of dissolving almost anything — wax, rocks, metals even platinum , and yes, even glass. Fluoroantimonic acid is the strongest super-acid known in existence.

Copper oxidizes over time to form a green patina, which actually protects the metal from further corrosion. Metallic acid-resistant materials include wrought and cast high-alloy steels; nickel-, copper-, and aluminum-based alloys; and certain pure metals, such as nickel, aluminum, copper, and lead. The use of titanium and its alloys has promising possibilities.

You may think that well-known corrosion-resistant metals like copper, bronze, and brass might pull it off but the truth is they, too, will corrode when dipped in salt solution.

Thread starter amosfella Start date May 26, Title says it all Would HCl-Cl dissolve brass or copper?? Joined Feb 25, Messages 8, It rapidly dissolves the zinc contained in the alloy, so even if you don't achieve a fast dissolution of the entire body, it is degraded. While I have not ever used any of the work-around processes that are widely supported on this forum, seems to me the addition of a small amount of hydrogen peroxide is all it takes for HCl to dissolve copper readily.

Might pay you to do a search on the subject. If I am mistaken, feel free to post a correction. I was looking for a method to strip gold plating from brass without dissolving the brass or copper underneath Preservation of the substrate is not an issue Just want the cleanest way to get the gold Joined Mar 12, Messages 4, Location Philadelphia. What is it you are trying to strip?
