The chemical formula are:
(a) Aluminium carbonate
\(Al^{3+}\) \(CO_3^{2-}\)
Formula → \(Al_2(CO_3)_3\)
(b) Calcium sulphide
\(Ca^{3+}\) \(S^{2-}\)
CaS
(c) Zinc carbonate
\(Zn^{2+}\) \(CO_3^{2-}\)
ZnCO3
(d) Copper phosphate
\(Cu^{2+}\) \(PO_4^{3-}\)
Cu3(PO4)2
(e) Magnesium bicarbonate
\(Mg^{2+}\) \(HCO_3^{-}\)
Mg(HCO3)2
(f) Aluminium hydroxide.
\(Al^{3+}\) \(OH^{-}\)
Al(OH)3
