Give a brief description of the medical uses of the following ionic compounds: $\mathrm{AgNO}_{3}, \mathrm{BaSO}_{4}, \mathrm{CaSO}_{4}, \mathrm{KI}$,
$\mathrm{Li}_{2} \mathrm{CO}_{3}, \mathrm{Mg}(\mathrm{OH})_{2}, \mathrm{MgSO}_{4}, \mathrm{NaHCO}_{3}, \mathrm{Na}_{2} \mathrm{CO}_{3}, \mathrm{NaF}$
$\mathrm{TiO}_{2}, \mathrm{ZnO}$. You would need to do a Web search of some of these compounds.
