If I take Tri Sodium Phodphate (P2O5), Copper Sulphate (CuSO4) and Sodium Hydroxide (NaOH), than what would be the quantity to make stable Copper Hydroxide [Cu(OH)2].

  1. Even though this is more of a chemistry question than an agriculture one...

    Copper(II) hydroxide can be produced by adding a small amount of sodium hydroxide to a dilute solution of copper(II) sulfate (CuSO4 · 5H2O). The precipitate produced in this manner, however, often contains an appreciable amount of sodium hydroxide impurity and a purer product can be attained if ammonium chloride is added to the solution beforehand. Alternatively, copper hydroxide is readily made by electrolysis of water (containing a little electrolyte such as sodium bicarbonate). A copper anode is used, often made from scrap copper.
