Solubility of Iodide Compounds

The video tutorial explores the solubility of calcium iodide (CaI2) in water. It begins by introducing the concept of solubility and the importance of solubility rules. The instructor explains that compounds with chloride, bromide, or iodide ions are generally soluble, with exceptions like silver, lead, or mercury iodide. Calcium iodide is confirmed to be soluble in water. The video also demonstrates how to use a solubility table to verify this information, showing that calcium iodide is indeed soluble. The tutorial concludes by reiterating the solubility of calcium iodide in water.

What is the general rule for the solubility of compounds containing iodide ions?

• They are always insoluble.

• They are insoluble with some exceptions.

• They are soluble with some exceptions.

• They are soluble only in hot water.

Which of the following ions is an exception to the solubility of iodide compounds?

• Potassium

• Silver

• Sodium

• Calcium

How can you confirm the solubility of calcium iodide using a solubility table?

• By looking at the pH level.

• By checking the temperature column.

• By finding calcium and iodide ions and checking their intersection.

• By checking the pressure column.

What does the 'S' symbol indicate in a solubility table?

• The compound is volatile.

• The compound is insoluble.

• The compound is soluble.

• The compound is slightly soluble.

What is the final conclusion about the solubility of calcium iodide in water?

• It is only soluble in acidic solutions.

• It is only soluble at high temperatures.

• It is soluble.

• It is insoluble.
