In order to prepare a buffer solution of pH5.74, sodium acetate is added to acetic acid. If the concentration of acetic acid in the buffer is 1.0 M, the concentration of sodium acetate in the buffer is ______M. (Round off to the Nearest Integer). Given: pKaacetic acid=4.74

Solution

pH=pKa+log[CB][WA]
5.74=4.74+log[CB]1
⇒[CB]=10M

CB =Conjugate base.

WA =Weak acid
