Let me start you off, but you have to figure it out from there.
pH = pKa + log ([A-]/[HA])
Solve for ([A-]/[HA]). So you may set it up as
pH = pKa + log x
Now, solve for x...
The ionization constant of HA is 1 × 10−6
.
What must be the ratio of [A−] to [HA] for
the preparation of a buffer solution with a pH
of 6.77?
whats the answeer??????
