The white color of barium sulfate (BaSO₄) disappears upon the addition of aqueous hydrochloric acid (HCl) because HCl reacts with barium sulfate to form soluble barium chloride (BaCl₂) and sulfuric acid (H₂SO₄). The dissolution of BaSO₄, which is a white precipitate, results in the loss of its characteristic color. The reaction effectively removes the solid phase of barium sulfate from the mixture, leading to a clear solution.

Why does magnesium displace copper from copper sulphate?
This is a simple displacement reaction - the more reactive magnesium displaces the less reactive copper from a solution of its salt. .... magnesium + copper sulphate ---> copper + magnesium sulphate Mg + CuSO4 ----> MgSO4 + Cu the blue colour of the copper sulphate will disappear and the silver coloured magnesium will be replaced by brown-red copper metal. Hope this helps. :)
