Question

write the empirical formula of at least four binary ionic compounds that could be formed from the following ions: zn^{2 +}, pb^{4 +}, f^{-}, o^{2 - }

Explanation:

Step1: Combine Zn²⁺ and F⁻

The compound is formed to balance charges. For Zn²⁺ and F⁻, we need 2 F⁻ to balance the +2 charge of Zn²⁺, so the formula is ZnF₂.

Step2: Combine Zn²⁺ and O²⁻

The charges of Zn²⁺ and O²⁻ are equal in magnitude but opposite in sign, so the formula is ZnO.

Step3: Combine Pb⁴⁺ and F⁻

To balance the +4 charge of Pb⁴⁺, we need 4 F⁻, so the formula is PbF₄.

Step4: Combine Pb⁴⁺ and O²⁻

For Pb⁴⁺ and O²⁻, we need 2 O²⁻ to balance the +4 charge of Pb⁴⁺, so the formula is PbO₂.

Answer:

ZnF₂, ZnO, PbF₄, PbO₂
