Question

Derive acid buffer equation .it calculate the ph and log of buffer solution

Answer 1

Answer:

Here is your answer.

buffer is an aqueous solution designed to maintain a constant pH, even when exposed to small amounts of acids or bases. Whether acidic (pH < 7) or basic (pH > 7), a buffer solution consists of a weak acid or base mixed with the salt of its conjugate base or acid, respectively. To calculate the specific pH of a given buffer, you need to use the Henderson-Hasselbalch equation for acidic buffers: "pH = pKa + log10([A-]/[HA])," where Ka is the "dissociation constant" for the weak acid, [A-] is the concentration of conjugate base and [HA] is the concentration of the weak acid.

For basic (a.k.a. alkaline) buffers, the Henderson-Hasselbach equation is "pH = 14 - (pKb + log10([B+]/[BOH]))," where Kb is the "dissociation constant" for the weak base, [B+] is the concentration of conjugate acid and [BOH] is the concentration of the weak base.
