Dear Richards, It is strange that you've disapproved my reply.

Those Pka values are not my own numbers.

They are taken from "Lange's Hand Book of Chemistry".

If you want i'll send the scanned pages of these values to your mail id.

please approve only after you satisfy with the scanned pages.

 

Thanks dear

yours in the cause of education,

S.N.Sharma
