Question
Precentage ionisation of weak acid can be calculated using the formula:
Options
A.100 
B.
C.Both (A) and (B)
D.None of these
Solution
α = 
∴ % α = 100
Also Ka = 
log Ka = logH+ + log
or pKα = pH + log 
or pKa - pH = log
∴ 
= 10pKa - pH
or
= 10pKa - pH + 1 or α = 
∴ % α = 100 Also Ka = log Ka = logH+ + log
or pKα = pH + log or pKa - pH = log
∴ = 10pKa - pHor
= 10pKa - pH + 1 or α = Create a free account to view solution
