Question

a metal X when dipped in aluminium sulphate no reaction takes place.where as when dipped in aqueous solution of copper sulphate the blue colour of the solution disappear.identify metalX explain reason with chemical reaction

Answer 1

zinc
because of order of reactivity of metals
So, here , on adding zinc to CuSO4 solution, zinc displaces copper fromcopper sulphate & forms zinc sulphatesolution. This is indicated by colourchange from blue to colourless. CuSO4 solution has a blue colour while ZnSO4 solution is colourless. Zn(s) + CuSO4(aq) -> Cu(s) + ZnSO4 (aq).
