write a balanced chemical equation to represent and aqua sodium hydroxide solution that is added to a copper sulphate solution forms a bluish white precipitate of copper hydroxide |
Answer» Answer :-It is given that aqueous SODIUM HYDROXIDE (NaOH) solution is added to copper sulphate solution (CuSO₄) , and forms a bluish white precipitate i.e. Copper Hydroxide [Cu(OH)₂] . Another product, which is formed in this REACTION is aqueous solution of Sodium Sulphate (Na₂SO₄) . NaOH + CuSO₄ → Cu(OH)₂ + Na₂SO₄ [skeletal equation] ______________________________ On observing the above equation carefully, we will understand that the equation will be balanced if we multiply "NaOH" on the REACTANT side with 2 . 2NaOH + CuSO₄ → Cu(OH)₂ + Na₂SO₄ [balanced equation] . The obtained balanced equation will be more informative if we add "symbols of physical states" of the reactants and the products. So, here we write it :- 2NaOH (AQ) + CuSO₄ (aq) → Cu(OH)₂ (s) + Na₂SO₄ (aq) |
