Step 1:I'll solve this step by step using the specified LaTeX formatting guidelines:
Step 2:: Understand the Chemical Naming Rules
- Hydroxide is the $$\mathrm{OH}^{-}$$ ion
- Iron(III) indicates the oxidation state of iron is + 3 - We need to create a neutral compound by balancing the charges
Step 3:: Determine the Charge Balance
- To create a neutral compound, we need 3 hydroxide ions to balance the $$+3$$ charge
- Hydroxide ion has a charge of - 1
Step 4:: Write the Chemical Formula
- The formula will be $$\mathrm{Fe(OH)_{3}}
- This means one iron atom with three hydroxide ions
Step 5:: Verify the Compound
- $$\mathrm{Fe}^{3+}$$ combines with $$3 \times \mathrm{OH}^{-}
- Resulting in a neutral, balanced compound
Final Answer
d. \mathrm{Fe(OH)_{3}}
