Post Utme Unn 2017 Chemistry Question 26
Practice objective / multiple choice question 26 from the 2017 Post Utme Unn Chemistry examination.
A solution of potassium dichromate (K2Cr2O7) is titrated with iron(II) sulfate (FeSO4) in the presence of dilute sulfuric acid (H2SO4). The reaction is as follows: K2Cr2O7 + 6FeSO4 + 7H2SO4 → K2SO4 + 3Cr2(SO4)3 + 6Fe2(SO4)3 + 7H2O. If 25.0 mL of 0.100 M K2Cr2O7 is titrated with 0.0500 M FeSO4, what is the volume of FeSO4 required to reach the equivalence point?
