Question

Which is NOT a property of buffers? Buffers resist changes in pH when acids or bases are added or when dilution occurs. Buffers are a mixture of weak acid and conjugate base. The pH of a buffer is independent of ionic strength. The pH of a buffer is dependent on temperature. Buffers are a mixture of weak bases and conjugate acid. A buffer is prepared by mixing 200.0 mL of 0.1500 M NaOH with 200.0 mL of 0.200 M CH_3CO_2H in a 1-L volumetric flask and then diluted to volume with distilled deionized water. Calculate the pH of the buffer. K_a=1.75x times 10^-5 5.23 9.72 7.00 8.77 4.28

Explanation / Answer

1)

acidic buffer is formed by weak acid and salt of weak acid
basic buffer is formed by weak base and salt of weak base
They resist change in pH
Also pH is dependent on temperure
pH is also dependent on ionic strength
