Copper(I) oxide also makes sense due to the reducing environment in which the compound was formed.
Here are some properties of my compound
- It only grudgingly dissolves in aqueous ammonia with a lot of shaking, forming the familiar tetraammine copper(II) complex.
-It turns tan to red-brown upon drying in air
-It will not dissolve to any degree in boiling household vinegar(I tried this because copper(II) carbonate will)
-It forms a superfine, powdery, copper-colored precipitate upon treatment with phosphoric acid. Perhaps it could be copper metal?
Very regrettably I do not have hydrochloric acid at this time to find out if mine reacts similarly to yours, but if you're trying to identify this
compound, you might want to produce what I've got and see if they match up. |
