Question
A certain buffer solution contains equal concentration of X- and HX. The Kb for X- is 10-10. The pH of the buffer is :
Options
A.4
B.7
C.10
D.14
Solution
According to Handerson′s equation
pH = pKα + log10
and Ka =
= 10-4, and [salt] = [Acid]
∴ pH = - log 10-10 + log10
= 4 
pH = pKα + log10
and Ka =
= 10-4, and [salt] = [Acid]∴ pH = - log 10-10 + log10
= 4 Create a free account to view solution
