A test solution contained 2 mL of 0.10 M Ag+. A silver strip was dipped into the test solution, and a cell potential of 0.0592 V was measured against an Ag/Ag+(1.0M) reference half-cell. Then 2 mL of 0.50 M S2O32- was added to the test solution. No precipitate formed. The cell potential of the test solution was measured against the reference half-cell, and was found to have increased to 0.532 V. What is the [Ag+] in the test solution after the S2O32- was added?
