Presentation transcript:

pH pH scale- measure of H+ ions (acidity); “power of hydrogen” #10. H + = hydronium ion OH- = hydroxide ion

pH acid- lots of H+ ions taste sour feel watery #11.

pH base- lots of OH- ions taste bitter feel slippery #12.

pH neutral- equal amounts of H+ and OH- ions Ex: water neutralize- combining an acid and a base to form water #13.

pH buffer- any substance that resists a change in pH Many life biological reactions have a small pH range Example: blood (pH 7.35 – 7.45) buffering capacity- the ability to resist a change in pH #14. #15.
