How to calculate the ksp value for hg2i2

Reference no: EM13530478

To determine the Ksp value of Hg2I2, a chemist obtained a solid sample of Hg2I2 in which some of the iodine is present as radioactive 131I. The count rate of the Hg2I2 sample is 5.0 x 10^11 counts per minute per mole of I. An excess amount of Hg2I2 (s) is placed into some water, and the solid is allowed to come to equilibrium with its respective ions. A 150.0-mL sample of the saturated solution is withdrawn and the radioactivity measured at 33 counts per minute. From this information, calculate the Ksp value for Hg2I2.

Hg2I2 (s) [**double arrow, reversible reaction**] Hg2 with a charge of +2 (aq) + 2I with a charge of -1 (aq)

Ksp = [Hg2 with a charge of +2][I with a charge of -1]^2
