1. The problem statement, all variables and given/known data Stupid question but I'm not sure about it. In lab we added I3- and KI into a test tube and from this we have find the concentration of I3- in the final volume. 3. The attempt at a solution Would the I3- be diluted by the KI that was added or does the KI end up forming i3- once in solution? I know that I- will form I3- if I2 is present but what about if just I3- is present. Originally I just calculated the concentration assuming the I3- would be diluted by the volume of KI but my professor said that was not correct... Any help would be really appreciated.
