Please answer all parts.
4. 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 iven p calculate the new pH after a particular quantity of acid or base is ad You are given 60...
