what will you observe when dilute. hcl is added to small amount of copper oxide in a beaker |
|
Answer» When HCl reacts with copper oxide, a blue green solution of copper (II) chloride is formed. The reaction is as follows:\xa0HCl (aq) + CuO(s) → CuCl2 (aq) + H2O(l)This is a double replacement reaction. The soluble Copper(II)Chloride is blue-green in color and is responsible for the color of the solution formed.\xa0 No reaction will take place....as coper is less reactive than hydrogen it can\'t displace it... Copper chloride and water will be formed |
