B) In a laboratory procedure for preparing ZnSO4, a solid X was
added with stirring to warm, dilute H2SO4 until no more of it
dissolved: Excess of X was removed from the reaction
mixture. The solution of ZnSO4 obtained was concentrated
to a small volume and then set aside.
(i) Suggest three substances which X could be.
(ii) Name the method used for removing excess of X.
(iii) What method was used to concentrate the ZnSO4
A(aq)
4(aq)
(iv) State what later appeared in the concentrated Znso,
that was set aside.
