Find out the solubility product constant

Reference no: EM13214055

A titration was performed to determine the solubility product constant (Ksp) of an unknown iodide with formula . The first two steps of the reaction sequence are shown below:

These two reactions added together give rise to the following overall reaction:

20.00 mL of a saturated solution was titrated with 5.85×10?2 M . The first step of the reaction sequence was performed and a starch indicator was added to the solution turning it blue. After 1.77mL of the was added the endpoint was established as the blue color indicating the presence of turned clear.

From the results of these experiments, calculate the Ksp of the unknown iodide. Report your answer to three significant figures.
