19 The PH Scale The pH Scale is a measurement of how acidic or how basic a solution is. The scale goes from 0 to 14.

20 The PH Scale The pH Scale is a measurement of how acidic or how basic a solution is. The scale goes from 0 to 14.

21 The PH Scale The pH Scale is a measurement of how acidic or how basic a solution is. The scale goes from 0 to 14.

35 Buffers A buffer is a weak acid or base that prevents sudden changes in pH. Maintains homeostasis

36 Buffers A buffer works by binding to H+ ions releasing H+ ions when the solution pH changes.

37 Buffers A buffer works by binding to H+ ions releasing H+ ions when the solution pH changes.

38 Buffers A buffer works by binding to H+ ions releasing H+ ions when the solution pH changes.

39 Buffers Buffers bind to H+ ions when the concentration of H= ions in solution increases. NaOH  Na + + OH - (The OH- will bind to H+ ions to form H 2 O – neutralization)

40 Buffers Buffers bind to H+ ions when the concentration of H= ions in solution increases. NaOH  Na + + OH - (The OH- will bind to H+ ions to form H 2 O – neutralization)

41 Buffers Buffers bind to H+ ions when the concentration of H= ions in solution increases. NaOH  Na + + OH - (The OH- will bind to H+ ions to form H 2 O – neutralization)

42 Buffers Buffers bind to H+ ions when the concentration of H= ions in solution increases. NaOH  Na + + OH - (The OH- will bind to H+ ions to form H 2 O – neutralization)

43 Buffers Buffers bind to H+ ions when the concentration of H= ions in solution increases. NaOH  Na + + OH - (The OH- will bind to H+ ions to form H 2 O – neutralization)

44 Buffers Buffers bind to H+ ions when the concentration of H= ions in solution increases. NaOH  Na + + OH - (The OH- will bind to H+ ions to form H 2 O – neutralization)
