Unit 8 · Acids and Bases

Chapter 8.5

Buffers: Resisting pH Change

Your blood is hit with acid every time you exercise, and its pH moves by a few hundredths. A solution holding both members of a conjugate pair absorbs acid and base alike, up to a limit.

in preparation · lesson 39 of 45

By the end

  1. 01Explain how a conjugate pair consumes added acid or base to hold pH steady
  2. 02Compute a buffer's pH from pK_a and the base-to-acid ratio
  3. 03Relate buffer capacity to the amounts and ratio of the conjugate pair
