Starting from insoluble ZnO how would you obtain insoluble ZnCO 3 by precipitation.

ZnO + 2HCl ZnCl 2 + H 2 O ZnCl 2 + Na 2 CO 3 ZnCO 3 + 2NaCl Dissolve zinc oxide in dil. HCl. Add to it a saturated solution of Na 2 CO 3 . The precipitate formed by the interchange of radicals is filtered. It is dried to obtain the zinc carbonate.
