Which of the following statements about buffers is true?

#SCPH05 I Biotechnology

A buffer composed of a weak acid of pKa = 5 is stronger at pH 4 than at pH 6.
At pH values higher than the pKa, the salt concentration is higher than that of the acid.
The strongest buffers are those composed of strong acids and strong bases.
When pH = pKa, the weak acid and salt concentrations in a buffer are equal.
