Question

7. Degree of dissociation of weak acid and weak base
are the same. If 0.001 M solution of weak acid has
pH = 5.0 then the pH of 0.001 M weak base is​

Answer 1

Answer:

a is degree of dissociation

same for both

for weak electrolyte

[H+]=C1a1 and [OH-]=C2a2

from given C1=C2

[H+]= [OH-]

pH (for acid)=pOH (for base)

pOH=5

as pH+pOH=14

pH (for base)=14-5=11
