Question
0.5M of a weak acid (HA) and 0.5M of its conjugate base (A) are mixed such that the composition of the buffer is 40% acid
0.5M of a weak acid (HA) and 0.5M of its conjugate base (A) are mixed such that the composition of the buffer is 40% acid and 60% conjugate base. The pH of this buffer will be:
a.) Lower than the pKa value of the weak acid
b.) Higher than the pKa value of the weak acid
c.) Same as the pKa value of the weak acid
