Question

Chemical formula of lead sulphate and lead nitrate is __________ respectively.

• A. $P{b}_2\left(S{O}_4\right)$, $P{b}_2\left(NO\right)$
• B. $Pb(SO{)}_4$, $Pb(NO{)}_2$
• C. $Pb(SO{)}_4$, $Pb(N{O}_3{)}_2$
• D. $P{b}_2(S{O}_4{)}_3$, $Pb(N{O}_3{)}_2$

Answer 1

The correct option is C $Pb(SO{)}_4$, $Pb(N{O}_3{)}_2$

$\bullet$ Lead sulphate consist of lead ion and sulphate ion, i.e., $P{b}^{2+}$ and $S{O}_4^{2-}$.

$\bullet$ Lead nitrate consist of lead ion and nitrate ion, i.e. $P{b}^{2+}$ and $N{O}_3^{-}$.For lead sulphate:

Symbol	$P{b}^{2+}$	$S{O}_4^{2-}$
Charge	+2	-2

For lead nitrate:

Symbol	$P{b}^{2+}$	$N{O}_3^{-}$
Charge	+2	-1

$\bullet$ On cross-multiplication and balancing the charge, we get the formulae as $PbS{O}_4$ and $Pb(N{O}_3{)}_2$.
