Question

y) zinc hydrogen sulphate
z) fe₂(so₄)₃

Explanation:

To determine the name of the compound with the formula $\ce{Fe_{2}(SO_{4})_{3}}$, we analyze the ions present:

Step 1: Identify the ions

• The cation is $\ce{Fe^{3+}}$ (iron(III) ion, since the subscript of $\ce{Fe}$ is 2 and the subscript of $\ce{SO_{4}^{2-}}$ is 3; to balance charges: $2\times(+3) + 3\times(-2) = 0$).
• The anion is $\ce{SO_{4}^{2-}}$ (sulfate ion).

Step 2: Combine the ion names

The cation is iron(III) (to indicate the +3 charge on $\ce{Fe}$), and the anion is sulfate. Combining these, the name of $\ce{Fe_{2}(SO_{4})_{3}}$ is iron(III) sulfate (or ferric sulfate).

Answer:

iron(III) sulfate (or ferric sulfate)
