! Do bases always have to react with acids to make salt and water or can they make salt and hydrogen instead? For instance, I heard that some metal bases react with acids to form salt plus hydrogen. Would those metals simply not be considered bases or can bases form hydrogen as a product instead of water?

Depends on the base:. Base are proton acceptors. For gcse, bases are metal oxides, metal carbonates, metal hydroxides, (ammonia, A Level) Metal oxide + acid -> salt + water Metal hydroxide + acid -> salt + water Metal carbonate + acid -> salt + water + carbon dioxide You are thinking of a metal and a acid. Metals on their own are not a base Metal + acid -> salt + hydrogen
The definition of a salt is the H+ in the acid is replaced by the metal or ammonium ion.
