In copper sulfate, CuSO4, the oxidation state of copper (Cu) is +2.
To determine the oxidation state of an element in a compound, you can use some general rules:
The oxidation state of a monatomic ion is equal to its charge. In this case, sulfate (SO4^2-) is a polyatomic ion with a charge of -2.
The sum of the oxidation states of all atoms in a neutral compound is equal to zero.
So, if you let x represent the oxidation state of copper (Cu), you can set up the following equation:
x + 4(-2) = 0
Solving for x:
x - 8 = 0
x = 8
Therefore, the oxidation state of copper (Cu) in CuSO4 is +2.
