Question

write the empirical formula for at least four ionic compounds that could be formed from the following ions: pb^{4+}, no_{3}^{-}, io_{3}^{-}, fe^{3+}

Explanation:

Step1: Combine \(Pb^{4 +}\) with \(NO_{3}^{-}\)

The charge of \(Pb^{4+}\) is \(+ 4\) and the charge of \(NO_{3}^{-}\) is \(-1\). To balance the charges, we need \(4\) \(NO_{3}^{-}\) ions for each \(Pb^{4+}\) ion. So the formula is \(Pb(NO_{3})_{4}\).

Step2: Combine \(Pb^{4 +}\) with \(IO_{3}^{-}\)

The charge of \(Pb^{4+}\) is \(+4\) and the charge of \(IO_{3}^{-}\) is \(-1\). To balance the charges, we need \(4\) \(IO_{3}^{-}\) ions for each \(Pb^{4+}\) ion. So the formula is \(Pb(IO_{3})_{4}\).

Step3: Combine \(Fe^{3 +}\) with \(NO_{3}^{-}\)

The charge of \(Fe^{3+}\) is \(+3\) and the charge of \(NO_{3}^{-}\) is \(-1\). To balance the charges, we need \(3\) \(NO_{3}^{-}\) ions for each \(Fe^{3+}\) ion. So the formula is \(Fe(NO_{3})_{3}\).

Step4: Combine \(Fe^{3 +}\) with \(IO_{3}^{-}\)

The charge of \(Fe^{3+}\) is \(+3\) and the charge of \(IO_{3}^{-}\) is \(-1\). To balance the charges, we need \(3\) \(IO_{3}^{-}\) ions for each \(Fe^{3+}\) ion. So the formula is \(Fe(IO_{3})_{3}\).

Answer:

\(Pb(NO_{3})_{4}\), \(Pb(IO_{3})_{4}\), \(Fe(NO_{3})_{3}\), \(Fe(IO_{3})_{3}\)
