Answer to Question #86224 in General Chemistry for jason
Question #86224
Potassium dichromate in acidic solution is used to titrate a solution of copper(I) ions, with which it reacts according to
Cr2O72(aq) + 6Cu(aq)+14H3O(aq)-----2Cr3(aq) + 6Cu2(aq)+21H2O(l)
A potassium dichromate solution is prepared by dissolving 32.18 g of K2Cr2O7 in water and diluting to a total volume of 1.000 L. A total of 19.93 mL of this solution is required to reach the endpoint in a titration of a 250.0-mL sample containing Cu+(aq). Determine the concentration of Cu+ in the original solution.
