What should be done with the used of copper chloride etching solutions?

Copper has high biotoxicity and cannot be removed adequately by sewage plants, so while it is common for electronics hobbyists to flush it down the drain this should be avoided (although the amount in used by hobbyists is probably minor).
I have read that adding aluminum foil to the solution prior to disposal will precipitate the metallic copper creating nontoxic aluminum chloride. Filter out the copper flakes and pour the remaining liquid down the drain.

How might a scientist distinguish the following compounds strontium chloride and potassium chloride?
If you heat something containing strontium until it glows it should tend to glow red. If you heat something containing potassium until it glows it should tend to glow yellow.
Solutions to circus abuse?
A law should be passed saying that the animals in circuses, while being trained, should not in any way be harmed.
Does strontium chloride have a ionic or covalent bond?
It is ionic as are all strontium compounds.
Should a kid be able to play with silica jell?
No, while colorless silica gel is non-toxic, the dopants used as color moisture indicator in silica gel (such as cobalt (II) chloride) are carcinogens and are quite toxic.
How is gold used in electronics?
Gold is used as a conductor of electricity on flash drives, USB cables, etc. It plates the metal surface to let the most electricity flow. The question should be why not how. Gold is impervious to oxidation and a very good conductor. So connections are more reliable if made with gold contacts as opposed to copper which oxidizes easily.
What can be used to split copper chloride into copper and chlorine?
A solution of copper chloride should be electrolyzed.

Why copper sulphate not used in flame test?
A.o.A it is the demand of flame test that salt should be easily vapourised as metalic chloride for this purpose we wet the given salt with acid (HCl) so that it change into chloride but copper cannot remove hydrogen(As Au,Ag,Pt) from acid so cannot changed into chloride and not used in flame test. but if there is chloride salt of copper it can be easily used for flame test with-out use of acid.....
What is the difference between copper and chloride and copper chloride?
Carbon Steel is much stronger metal.
What happens when you put copper in salt water?
When copper is placed in salt water, a chemical reaction causes the copper to turn a blue-green color: this is called copper chloride. If you leave copper in salt water long enough beside the change of color, you should also see a blue-green film or powder appear. This is normal.
Does liquid solution have to be cloudy?
Yes, solutions have to be clear and cannot be cloudy, this means that they are always transparent and you can see through them. The word 'clear', however, should not be confused with the word 'colourless' as some solutions, like copper sulphate solution which is blue, maybe be coloured but they will still be clear or transparent.
What happens to the oxygen in a copper chloride aluminum reaction?
I don't know man, go ask someone else! Oh yeah, im only 11, how should I know?
What is the result when copper reacts with hydrochloric acid?
When copper reacts with hydrochloric acid it produces a metal salt. In this case the metal salt is copper chloride. It also produces hydrogen as a bi-product. You can test to see if it's hydrogen by taking a lit match and put it into the container you did to reaction in ( the container should be a boiling tube as some heat is produced during the reaction) You should hear a squeaky pop. That the hydrogen.
What happens when rubidium reacts with chloride?
Rubidium chloride, RbCl, should be formed.
What happens when silver nitrate is added to chloride?
silver chloride should precipitate out.
What is the pH of potassium Chloride?
Pure potassium chloride solution should have a pH about 7.
Why should base solutions be carbonate free?
Base solutions should be carbonate free because of carbonate interference. They can cause impurities and changes to the concentration in the solutions.
