The cuprous sulfide - Cu2S - is black.
The chemical formula for cuprous arsenide is Cu3As.
Cuprous salts are typically white or pale yellow in color.
The compound with the formula Cu2S is called copper(I) sulfide, also known as cuprous sulfide. It is an important semiconductor material with applications in photovoltaic cells and as a catalyst in various chemical reactions.
Formula: CuF
S^-22S
Cu2S
Reddish
colourless gas
it ranges from red to maroon
Lead sulphide is typically black or dark grey in color.
This equation is basically 2Cu + S => Cu2S. If it was cupric sulfide it would be Cu + S -----> CuS
It reacts with sulphur present in the atmsphere and forms silver sulphide which is black in colour
Pure zinc sulphide is white in colour and is used as white pigment. But it is usually black in colour due to the presence of impurities.
a cuprous ion has 28 electrons.
The chemical formula for cuprous fluoride is CuF.
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 chemical formula for cuprous arsenide is Cu3As.
