8. Acid - Substances in water that increase the concentration of hydrogen ions (H + ). Arrhenius, Bronstad-Lowry, or Lewis definition?

9. What is the Lewis definition of an acid and a base? Acid - an electron pair acceptor Base - an electron pair donor

10. What is the Bronstad Lowry definition of an acid and a base? Acid- neutral molecule, anion, or cation that donates a proton. Base- neutral molecule, anion, or cation that accepts a proton.
