Starting from insoluble ZnO how would you obtain insoluble ZnCO3 by precipitation.

Question 1

Question 2

ZnO (*) + 2HCl (aq) → ZnCl2 (aq) + H2O(l)

ZnCl2 (aq) + Na2CO3 (aq) → ZnCO3 (*) + 2NaCl (aq)

Dissolve zinc oxide in minimum quantity of dil. HCl. Add to it a saturated solution of Na2CO3 in water till no more precipitation takes place. Filter and dry the ZnCO3 so obtained.
