Some metals react with acids and when they do the products are hydrogen gas and a solution of the salt. A salt is a type of compound which is made when an acid reacts with certain metals.

“The metals essentially work in two different ways,” Moran says. Copper and cobalt stabilize an intermediate imine, and vanadium accelerates the reaction by increasing the acidity of a key C ...

is via the reaction of benzene with hot concentrated sulfuric acid. Benzenesulfonic acid is used to produce phenol by fusing it with sodium hydroxide or hydrolyzing one of its salts, usually sodium.

In addition, metal ... the citric acid then reacts with the hydroxyl group on the same molecule. A ring closure occurs in an intramolecular esterification (Fischer lactonization) reaction.
