Calculate E after 10.0 mL of titrant has been added
Calculate E after 25.0 mL of titrant has been added
Calculate E after 28.0 mL of titrant has been added
When aqueous hydrogen sulfide (H2S) is reacted with aqueous I3-, solid sulfur and aqueous I- form in acid solution.
Write a balanced equation for this reaction
25.00 mL of unknown H2S sample are added to 25.00 mL of 0.01044 M I3- solution. Then, excess I3- was titrated with 14.44 mL of 0.009336 M Na2S2O3. Calculate the [H2S] in the sample.
