The Henderson - Hasselbalch equation describes the p H of a solution under buffering conditions: p H = p K a + l o g

The Henderson-Hasselbalch equation describes the pH of a solution under buffering conditions:
pH=pKa+log([A-][HA])
where pH=-log([H+]eq) and pKa=-logKa*[A-]and HA are the molar concentrations of the basic and acidic components of the buffer, respectively. It is often of
practical importance to re-arrange the Henderson-Hasselbalch equation to express the ratio of bae-to-acid, [A-][HA], in terms of the pH. This allows scientists to determine the
appropriate base-to-acid ratio necessary to reach a desired pH.
Derive an expression for [A-][HA] in terms of pH and pKa, and select an equivalent equation from the list below. Be careful with negative signs!
[A-][HA]=10*(pH-pKa)
[A-][HA]=log(pKa-pH)
[A-][HA]=10(pH-pKa)
[A-][HA]=log(pH-pKa)
[A-][HA]=10*(pKa-pH)
[A-][HA]=pKa-pHlog
[A-][HA]=pH-pKalog
[A-][HA]=10(pKa-pH)
