Q. The Henderson's equation for acetic acid and sodium acetate buffer is given by the expression
Equilibrium
A
$PH = p K_{a}-\log \frac{\left[ CH _{3} COONa \right]}{\left[ CH _{3} COOH \right]}$
B
$pH = p K_{a}+\log \frac{\left[ CH _{3} COONa \right]}{\left[ CH _{3} COOH \right]}$
C
$pOH = pK _{a}-\log \frac{\left[ CH _{3} COONa \right]}{\left[ CH _{3} COOH \right]}$
D
$\left. pOH = p K_{a}-\log \frac{\left[ CH _{3} COOH \right]}{\left[ CH _{3} COONa \right.}\right]$
Solution:
Correct answer is (b) $pH = p K_{a}+\log \frac{\left[ CH _{3} COONa \right]}{\left[ CH _{3} COOH \right]}$
