Question

Write the chemical formulae of all the compounds that can be formed by the combination of following ions :

${\mathrm{Cu}}^{2+}$, ${\mathrm{Na}}^{+},{\mathrm{Fe}}^{3+},{\mathrm{Cl}}^{-},{{\mathrm{SO}}_{4^{}}}^{2-},{{\mathrm{PO}}_4}^{3-}$

Answer 1

The compound formed by ${\mathrm{Cu}}^{2+}$=${\mathrm{CuCl}}_2,{\mathrm{CuSO}}_4,{\mathrm{Cu}}_3{\left({\mathrm{PO}}_4\right)}_2$

The compound formed by${\mathrm{Na}}^{+}$=$\mathrm{NaCl},{\mathrm{Na}}_2{\mathrm{SO}}_4,{\mathrm{Na}}_3{\mathrm{PO}}_4$

The compound formed by ${{\mathrm{Fe}}_{}}^{3+}$=${\mathrm{FeCl}}_3,\mathrm{Fe}{\left({\mathrm{PO}}_4\right)}_3,\mathrm{Fe}\left({\mathrm{PO}}_{4_{}}\right)$
