Why is a buffer only effective within a certain pH range?
O A. A buffer is only effective when the ratio of weak acid to conjugate base is 1.
OB.
A buffer cannot be effective in an acidic and basic pH range.
O C. Buffers are destroyed outside of this range.
OD.
As the buffer resists pH changes its acid or base gets used up.
OE.
Buffers are made so that they are effective for a certain pH because chemists rarely encounter situations where a broader-
range buffer is necessary.
