Question
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)
Options
A.
B.
C.
D.
Solution
E1 = 
log [H+]
or pH1 = E1 / 0.059 = pKa + log
pH2 = E2 / 0.059 = pKa + log
or
= 2 pKa or pKa = 
log [H+] or pH1 = E1 / 0.059 = pKa + log
pH2 = E2 / 0.059 = pKa + log
or
= 2 pKa or pKa = Create a free account to view solution
