Ionic Bonding Post-Lab

Draw the electron dot diagram for the ionic bond formed by Magnesium and Chlorine

Draw the electron dot diagram for the ionic bond formed by Aluminum and Chlorine

Draw the electron dot diagram for the ionic bond formed by Magnesium and Sulfate

Draw the electron dot diagram for the ionic bond formed by Aluminum and Sulfate

Describe the evidence that a precipitate formed in your polyatomic ion tests

Write the chemical formula and name for each ionic compound formed during the lab.

Explain how these reactions illustrate ionic bonding in the products. Reference cation charge (Mg²⁺ , Al³⁺) and anions (Cl⁻, SO₄²⁻).

Evaluate how charge balance determines the correct chemical formula of an ionic compound. Give one example from your data.

How can the evidence of ionic compound formation be confirmed through conductivity testing?

Match each compound with its correct name:

• calcium fluoride

• LiF

• calcium bromide

• LiBr

• lithium bromide

• CaBr₂

• lithium chloride

• CaF₂

• lithium fluoride

• LiCl
