Answer to Question #75998 in Inorganic Chemistry for Mannu

Question

Which metals are called class'a' elements or 'hard acids 'and why?

Answer 1

Class A metals are metals that form solid acids. Solid acids are acids with relatively ionic bonds. These metals, such as iron, aluminum, titanium, sodium, calcium and lanthanides, are more likely to be associated with fluorine than with iodine. They form stable products with solid bases that are bases with ionic bonds. They target molecules such as phospholipids, nucleic acids, and ATP.
