Question 22

Easy

The reaction between iron(II) ions and dichromate(VI) ions in acidic solution can be represented by the equation:

6\text{Fe}^{2+} + \text{Cr}_2\text{O}_7^{2-} + 14\text{H}^+ \rightarrow 6\text{Fe}^{3+} + 2\text{Cr}^{3+} + 7\text{H}_2\text{O}

What volume, in $dm3\text{dm}^3$ , of 0.050 mol dm^-3 $K2Cr2O7\text{K}_2\text{Cr}_2\text{O}_7$ is needed to oxidise 0.15 mol of iron(II) ions completely?

$0.025$

$0.15$

$0.50$

$3.0$
