Question
Which represents the formula for iron(II) chromate?
Group of answer choices
Fe2(CrO4)3Fe3(CrO4)2FeCrO4Fe3(CrO4)3
Solution
To determine the correct formula for iron(II) chromate, we need to consider the charges of the ions involved.
- Iron(II) indicates that iron has a +2 charge, represented as Fe²⁺.
- Chromate is a polyatomic ion with the formula CrO₄²⁻ and has a -2 charge.
Since the charges of Fe²⁺ and CrO₄²⁻ are equal and opposite, they will combine in a 1:1 ratio to balance the charges.
Thus, the correct formula for iron(II) chromate is FeCrO₄.
So, the correct answer is: FeCrO₄
