...Copper in moist air slowly acquires a dull green coating because its top layer has oxidised with the air. Some architects use this material on rooftops for the interesting colour. The green material is a 1:1 mole mixture of Cu2 and CuCO3:Masterson, W. L., & Hurley, C. N. (2004). Chemistry: Principals and Reactions, 5th Ed. Thomson Learning, Inc. (p 498). Read full entry

Could anyone please tell what CuCO3.Cu(OH)2.xH20. Anyone?
I need Malachite's only!
Thankyou.

For azurite, it's zero. Georgeite is Cu5(CO3)3(OH)2ยท6(H2O) |

How is basic copper sulphate copper sulphate is in solution
and basic copper sulphate is a
precipitate
Please provide chemical
equations.

I've never made basic copper sulfate in my little home lab. In fact, before I read this question I never knew it existed, only knew basic copper carbonate. Going on the 'Net netted me a description of basic copper sulfate. It's a fertilizer apparently. Formula's supposedly CuSO4*3Cu(OH)2*H2O. Unfortunately, I'm not sure how it would be formed from CuSO4 and some soluble carbonates. I'm not sure but I think that such a combination would be more likely to form basic copper carbonate, not sulfate, but I might be wrong. According to US Patent US3404951, (after you get past all the graphs) basic copper sulfate is formed by the "reaction of copper sulfate and sodium hydroxide in the presence of soluble basic phosphates" and supposedly has better anti-fungal properties than regular copper sulfate. So I'm not sure why the question asks for the use of metal carbonates instead of hydroxides. |

chemistry puzzle! urgent!?
There were 4 students. Rich
Curium, who planned to become
a medical doctor, and his
partner, Sue Crows, who hoped
to become a dietitian, were
trying to identify an unknown
salt. The other two, Kal E. M.
R. Snide, who hopped to become
a biologist some day, and
Celine Eumm, who hoped to
become a chemist, were trying
to filter a fine precipitate.
The teacher, Mr. Klamm, was
cracking the whip, trying to
get the students out of the
lab so he could go home to
dinner.
Suddenly there was a bright
flash. In through the door
flew four hideous creatures,
each astride a meter stick.
They all wore black lab coats
and green goggles, but they
had different hats. The first
witch had a conical hat made
of a sheet of Aluminum foil.

This is a great question and your teacher is awesome for taking the time to write it for you. The key is the fact that it was raining outside. So the chemistry question is, which of those four is soluble? |
