What is the chemical formula for cupric sulfide?
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)
How is cuprous iodide formed from potassium iodide?
Cuprous iodide can be formed from potassium iodide by mixing a solution of copper(II) sulfate with potassium iodide. The reaction between the two compounds results in the precipitation of cuprous iodide, which is a solid compound. This solid can then be filtered and dried to obtain cuprous iodide.
Is copper sulfate a metal?
Copper sulfate is not a metal There are two compounds called Copper Sulfate, which are salts of the metal Copper. CuSO4 is Copper (II) Sulfate, once known as Cupric Sulfate. Cu2SO4 is Copper (I) Sulfate, once known as Cuprous Sulfate.
How is cuprous iodide prepared?
React a solution of Copper(II) sulfate with Sodium Iodide. It will produce Copper(II) Iodide and Sodium sulfate. This Copper(II) iodide, due to instability, spontaneously decomposes, producing Iodine and Copper(I) Iodide.The Copper(I) iodide comes out as a yellowish brown precipitate. So the overall reaction seems to be:2 CuSO4 + 4 NaI ----> 2 CuI + 2 Na2SO4 + I2
What is the colour of cuprous sulphide?
The cuprous sulfide - Cu2S - is black.
How many electrons does cuprous ion have?
a cuprous ion has 28 electrons.
IF A solution of copper sulfate is a conductor what particle is serve as charge carrier?
In a solution of copper sulfate, the charge carriers that help it conduct electricity are the copper ions (Cu2+) and the sulfate ions (SO4 2-). These ions are free to move in the solution and carry electrical charge.
What is the chemical formula for cuprous fluoride?
The chemical formula for cuprous fluoride is CuF.
What is the chemical formula for cuprous nitrate?
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.
What is the chemical formula for Cuprous arsenide?
The chemical formula for cuprous arsenide is Cu3As.
What are the colors of cuprous salts?
Cuprous salts are typically white or pale yellow in color.
What number is the positive charge in a cuprous ion?
The charge on cuprous ion is +2. It is written as Cu2+.
