When you add 2.0ml of 0.50 MS2O32- to the 2.0 ml of 0.10silver nitrate, formation ofAg(S2O3)23- occured byequation Ag+ +2S2O32- <---->Ag(S2O3)23- Ecell increased even though formation of a solid was notobserved. a) Using the value Ecell = 0.71V, calculate the [Ag+] in the testsolution after equilibrium is reached. b). Setup a reaction table for equation above and calculate theformation constant forAg(S2O3)23- . Show yourcalculations with units and the correct number of significantfigures.
