1.What is the volume of 0.142 M K2Cr2O7 would be required to exactly react with 56.8 mL of 0.100 M Na2SO3 in acidic solution? The products contain Cr3+ and SO4 (2-)
2.The iron in a 5.700 g sample containing some Fe2O3 reduced Fe (2+) . The Fe(2+) is titrated with 11.41mL of 0.1420 M K2Cr2O7 in acidic solution ? Potassium a spectator ion. Caculate the percentage of Fe in the sample?
The unbalance equation is Fe+Cr2O7 yields Fe+Cr
3..What salt is formed in the reaction between 4.65 mol HI and 4.65 mol Fe(OH)3?
