A hydrogen electrode placed in a buffer solution of CH3COONa and CH3COOH in the ratios of x : y and y : x has electrode potential values E1 volts and E2 volts, respectively at 25ºC. The pKa values of acetic acid is (E1 and E2 are oxidation potentials)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
E1 = 
or
pH1 = E1 / 0.059 = pKa + log 
pH2 = E2 / 0.059
= pKa + log 
or
