Respuesta :
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.
Iron (II) iodide solution will comprise of the highest concentration of iodide ions.
What is Reference table F?
It is used to check the solubility of the metal compounds created. It tells if the compound should be soluble or insoluble in water. Here the mercury, silver, and the lead form should be insoluble complex along with the iodide ions. It means that there is the low concentration of the dissolved iodide ions.
Therefore, iron(II) iodide will have the highest concentration of iodide ions when dissolved in water.
