Correct Answer: A-2 B-3 C-1 D-4. Copper(II) sulfate, also known as Blue Vitriol, is used as a fungicide. Eosin is used as a red dye in inks; however, the molecule, especially that of eosin Y, tends to degrade over time, leaving behind its bromine atoms, hence causing paint incorporating such a dye to obtain a darker brown tinge over time. The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice. Metal phosphides, usually zinc phosphide, have been used as a means of killing rodents and are considered single-dose fast-acting rodenticides (death occurs commonly within 1–3 days after single bait ingestion). A bait consisting of food and a phosphide (usually zinc phosphide) is left where the rodents can eat it. The acid in the digestive system of the rodent reacts with the phosphide to generate the toxic phosphine gas.
