Anything above 7.0 is alkaline, anything below 7.0 is considered acidic. Acids corrode active metals. Even gold, the least active metal, is attacked by an acid, a mixture of acids called 'aqua regia,' or 'royal liquid.' When an acid reacts with a metal, it produces a compound with the cation of the metal and the anion of the acid and hydrogen gas. Bases release a hydroxide ion into water...
