Question

pH of an acidic buffer is given by
A. `pH = pK_(a) +log.(["salt"])/(["acid"])`
B. `pH = pK_(a) -log.(["salt"])/(["acid"])`
C. `pH = (1)/(2)pK_(a) +log.(["salt"])/(["acid"])`
D. `pH = log K_(a) +log.(["salt"])/(["acid"])`

Answer 1

Correct Answer - A
By Henderson equation
`pH = pK_(a) + log .(["salt"])/(["acid"])`
