When metals react with acids, a salt of the metal and hydrogen gas are formed. We can investigate the reactivity of different metals by placing samples in acid and comparing the results.

Small pieces of solid calcium metal are placed in two different concentrations of two different acids (hydrochloric acid and nitric acid). The calcium reacts most vigorously with the hydrochloric acid ...

Transition metals have long been used ... of two components -- one acting as a Lewis acid and the other as a Lewis base -- that are unable to fully react with each other due to spatial or ...

If there's a reaction, we'll pull it out ... That way, there's no further rusting from the acid because the acid does attack the metal slightly. Then it'll be pressure washed until all of the ...
