A chemical reaction. When these two substances mix together they create an entirely new substance rather than just a physical change of one original substance.
Assuming you mean a reaction between potassium (K) and copper(II) sulfate, your products would be potassium sulfate and copper in a single replacement reaction. Here's the equation:2K + CuSO4 --> K2SO4 + Cu
Mercury does not replace copper in a reaction between copper II sulfate and mercury because mercury is below copper in the reactivity level of the periodic table.
the diffrences in reaction of potassium, magnesium and copper
You have to notice what happens during the reaction and what products have been obtained.
The chemical formula (not equation) of copper(II) sulfate is CuSO4.
Assuming you mean a reaction between potassium (K) and copper(II) sulfate, your products would be potassium sulfate and copper in a single replacement reaction. Here's the equation:2K + CuSO4 --> K2SO4 + Cu
2Cu(SO4) + 4KI --> 2K2(SO4) + 2CuI + I2Copper Sulfate + 2 Potassium Iodide --> Potassium Sulfate + Copper Iodide + Iodine
copper sulfate and nitric acid
The reaction forms aluminum sulfate and frees copper.
Yes. This is part of the process of extracting copper to sell.
Mercury does not replace copper in a reaction between copper II sulfate and mercury because mercury is below copper in the reactivity level of the periodic table.
Any reaction occur when gold is put in copper sulfate.
Mercury, Iron or Nickel will not replace copper in a reaction between copper II sulfate and the metals because the metals are below copper in the reactivity level of the periodic table.
the diffrences in reaction of potassium, magnesium and copper
Mixing these two reagents would make a dilute solution of copper sulfate.
The reaction is dehydration.
Fe(s) + Cu2+(aq) --> Fe2+(aq) + Cu(s)
