Cupric is used when copper is in a +2 oxidation state while cuprous is used when copper is in a +1 oxidation state.
Cupric chloride refers to the compound CuCl2, where copper has a +2 oxidation state. Cuprous chloride refers to the compound CuCl, where copper has a +1 oxidation state. This difference in oxidation state affects the chemical and physical properties of these compounds.
These compounds can alternatively be named copper(I) and copper(II) oxides; these so-called "Stock system" names seem to be preferred by most current textbooks of chemistry over the designations cuprous and cupric.
Cu2O. Cuprous is Cu+, cupric is Cu2+. Those are old-school names. Copper(I) oxide is a better name.
This equation is basically 2Cu + S => Cu2S. If it was cupric sulfide it would be Cu + S -----> CuS
Cuprous bromide is CuBr (Copper(I) bromide) Compare to Cupric Bromide which is CuBr2 . (Copper(II) bromide).
Cupric chloride refers to the compound CuCl2, where copper has a +2 oxidation state. Cuprous chloride refers to the compound CuCl, where copper has a +1 oxidation state. This difference in oxidation state affects the chemical and physical properties of these compounds.
I think cuprous oxide has a charge of 1+, while cupric oxide has a charge of 2+. Cupric oxide is also more stable than cuprous oxide.
Copper (II) oxide or cupric oxide: CuO.Copper (I) oxide or cuprous oxide: Cu2O.
These compounds can alternatively be named copper(I) and copper(II) oxides; these so-called "Stock system" names seem to be preferred by most current textbooks of chemistry over the designations cuprous and cupric.
Actually, the answer Cu(NO3)2 is incorrect for cuprous nitrate. Cu(NO3)2 is in fact cupric nitrate. Cuprous nitrate is represented as CuNO3 alone.
The formula for cuprous sulfide is Cu2S. Copper (I) or cuprous has a +1 charge, whereas Sulfur has a charge of -2. Cu^(-1) + S^(-2) -> Cu2S (The subscript is 2)
No, it is either a red powder (cuprous oxide) or a black powder (cupric oxide)
Copper (I) Oxide or Cuprous Oxide
Cu2O. Cuprous is Cu+, cupric is Cu2+. Those are old-school names. Copper(I) oxide is a better name.
This equation is basically 2Cu + S => Cu2S. If it was cupric sulfide it would be Cu + S -----> CuS
Cuprous nitrate is a chemical compound with the formula CuNO3. It is a white, crystalline substance that is used in various analytical chemistry applications and as a catalyst in organic reactions. Copper(I) ions in cuprous nitrate can act as reducing agents in certain reactions.
Cuprous bromide is CuBr (Copper(I) bromide) Compare to Cupric Bromide which is CuBr2 . (Copper(II) bromide).
