question 2- all 4 parts. please type orwritr clearly thank
you!
2. Buffer capacity refers to the amount of acid or base a buffer can "absorb without a significant pH change. It is governed by the concentrations of the conjugate acid and base components of the buffer. A 0.5 M buffer can "absorb" five times as much acid or base as a 0.1 M buffer for a given pH change. In this problem you begin with a buffer of known...
