Based on Reference Table F, which solution will contain the highest concentration of
iodide ions?
A
lead iodide
silver iodide
mercury (II) iodide
iron (11) iodide

Iron (II) iodide solution will contain the highest concentration of  iodide ions. Option D is the right answer.

Explanation:

Reference table F is used to check the solubility of the metal compounds formed. It tells if the compound is soluble or insoluble in water.

From the table, it is seen that Mercury, silver and lead form insoluble complex with iodide ions. This means that they have low concentration of dissolved iodide ions. These three metals lead, silver and mercury are given as exception in the table F.

Thus iron(II) iodide will have highest concentration of iodide ions when dissolved in water.

the answer is a. co2, this would be colder than the : )
