In flushing and cleaning columns used in liquid chromatography to remove adsorbed contaminants, a series of solvents is used. Hexane, chloroform, methanol, and water are passed through the column in that order. rationalize the order in terms of intermolecular forces and the mutual solubility of the solvents.
A soluble iodide was dissolved in water. Then an excess of silver(I) nitrate, AgNO3 was added to completely precipitate out all the iodide ion as silver(I) iodide, AgI. if 1.545 grams of soluble iodide gave 2.185g of silver(I) iodide, then
