Questions: Provide the formula for each of the chemical names of the following ionic compounds: 1. Iron(III) sulfate 2. Copper(II) chloride 3. Potassium dichromate 4. Silver oxide 5. Magnesium phosphate

Solution Steps

Iron(III) sulfate consists of iron ions with a +3 charge (\(\text{Fe}^{3+}\)) and sulfate ions with a -2 charge (\(\text{SO}_4^{2-}\)). To balance the charges, two iron ions and three sulfate ions are needed, resulting in the formula \(\text{Fe}_2(\text{SO}_4)_3\).

Copper(II) chloride consists of copper ions with a +2 charge (\(\text{Cu}^{2+}\)) and chloride ions with a -1 charge (\(\text{Cl}^-\)). To balance the charges, one copper ion and two chloride ions are needed, resulting in the formula \(\text{CuCl}_2\).

Potassium dichromate consists of potassium ions with a +1 charge (\(\text{K}^+\)) and dichromate ions with a -2 charge (\(\text{Cr}_2\text{O}_7^{2-}\)). To balance the charges, two potassium ions and one dichromate ion are needed, resulting in the formula \(\text{K}_2\text{Cr}_2\text{O}_7\).
