The question ask for the species of the (i) glycine hydrochloride (ii) glycine titrated with NaOH. When they mentioned 'species', what did they mean by it?




The term species is used to describe a given type of atoms, molecules or ions. As a functional definition, a species is any atom, molecule or ion that could be part of a chemical reaction equation as reactant or product.


Here, it refers to the different protonation states of glycine, no matter whether anionic, neutral or cationic.
