The sodium chromate solution from problem 1 was used to titrate a solution made by dissolving 2.000 g of a pure ferrous sait in sulfuric acid. The titration required 39.56 mL. of the sodium dichromate solution. Calculate the percent by mass of iron in the pure salt.
The net ionic equation here is the same as in problem 1. You will not be able to write a balanced molecular equation for this because the anion in the ferrous salt was not specified in this problem.
