Trihalomenthanes 9. Acid: sour, litmus paper turn red, react with Carbonate to form CO 2 10. Base: bitter, slippery on skin, litmus paper turn blue 11. Arrhenius Theory a. Bases: hydroxide (OH-) donor b. Acid: proton donor 12. Bronsted-Lowry Theory a. Acids: proton donor b. Bases: proton acceptors 13. Amphoteric: act as acid or base 14. Neutralization reactions a.
