1. Statement 1: The oxidation number of hydrogen is -1 when bonded to non metals and +1 when bonded to metals Statement 2: The oxidation number fluorine is -1 in all compounds 2. Statement 1: Alkali metals and alkali Earth meters are least easily oxidized. Statement 2: Noble metals such as gold are most easily oxidized. 3. Statement 1: As titrants, multidentate ligands, generally react more completely with cations and thus provide sharper end points. Statement 2: As titrants, multidentate ligands, they ordinarily react with metal ion in a single step process, whereas complex formation with unidentate ligands usually involves 2 or more intermediate species. A - If the first statement is TRUE and the second statement is FALSE B - If the first statement is FALSE and the second statement is TRUE C - If both statements are TRUE D - If both statements are FALSE
Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.
