Neco 2022 Chemistry Question 45
Practice objective / multiple choice question 45 from the 2022 Neco Chemistry examination.
In an acidic medium, potassium dichromate reacts with iron(II) sulfate according to the balanced redox equation \(\mathrm{Cr_2O_7^{2-} + 6Fe^{2+} + 14H^+ \rightarrow 2Cr^{3+} + 6Fe^{3+} + 7H_2O}\). If 10.0 g of \(\mathrm{K_2Cr_2O_7}\) is completely consumed and excess \(\mathrm{H_2SO_4}\) provides sufficient \(\mathrm{SO_4^{2-}}\) ions, calculate the mass of iron(III) sulfate \(\mathrm{Fe_2(SO_4)_3}\) formed.
