Question

$P{b}^{2+},N_2,B,P{H}_3,Ag,I^{-}$

Name the compound formed from $P{b}^{2+}$ and $I^{-}$ ions and write a formula for it.

Answer 1

The given ions are $P{b}^{2+}$ and $I^{-}$. Here we need $2I^{-}$ ions to balance $+2$ charge of $P{b}^{2+}$. Therefore compound formed from their combination is $Pb{I}_2$ or Lead di Iodide.
