Practice: Which of the following compounds would produce the greatest concentration of hydrogen ions when dissolved?
Acids are covalent compounds with H+ ion connected to a nonmetal anion or polyatomic ion. Bases are ionic compounds with metal cation connected to OH- anion, although can also be N containing covalent compounds.
Intro to Acids and Bases
