Question

fill in the name and empirical formula of each ionic compound that could be formed from the ions in this table. some ionic compounds cation anion empirical formula name of compound pb²⁺ po₃³⁻ mg²⁺ so₄²⁻ zn²⁺ io₃⁻ co³⁺ clo⁻

Explanation:

Step1: Determine formula for $Pb^{2 +}$ and $PO_{3}^{3-}$

Cross - multiply charges to get $Pb_{3}(PO_{3})_{2}$.

Step2: Name the compound for $Pb^{2 +}$ and $PO_{3}^{3-}$

Lead(II) phosphite.

Step3: Determine formula for $Mg^{2+}$ and $SO_{4}^{2 -}$

Since charges are equal in magnitude, formula is $MgSO_{4}$.

Step4: Name the compound for $Mg^{2+}$ and $SO_{4}^{2 -}$

Magnesium sulfate.

Step5: Determine formula for $Zn^{2+}$ and $IO_{3}^{-}$

Cross - multiply charges to get $Zn(IO_{3})_{2}$.

Step6: Name the compound for $Zn^{2+}$ and $IO_{3}^{-}$

Zinc iodate.

Step7: Determine formula for $Co^{3+}$ and $ClO^{-}$

Cross - multiply charges to get $Co(ClO)_{3}$.

Step8: Name the compound for $Co^{3+}$ and $ClO^{-}$

Cobalt(III) hypochlorite.

Answer:
