Acid strength

Principle

There are different classes of acids, acids are generally divided into strong and weak acids. The strength of an acid can be distinguished (in the case of identical concentration of every acid) by the reaction rate when the acid reacts with metals (and dissolve them). In this experiment students study wether acids react at varying rates with metals.
