Explanation:
a)
Dilute sulfuric acid reacts with metals higher than hydrogen in the reactivity series to form sulfate salts and hydrogen gas. Note the metal reactions are different with concentrated sulfuric acid. Iron is cleaned free from rust prior to coating with tin to form tinplate and with zinc to form galvanized iron
thus he will notice sulfate salts and hydrogen gas
b)
ant bite contains formic acid. He must apply zinc carbonate to treat it
