1.	PH of 0.05 monobasic acid is 6.2. The % dissociation of it is?A) 1.29B) 0.029C) 2.12D) 0.04Please answer
Answer» Explanation: ph=6.2 so, Ka=10^-6.2 .......... {^}denotes = power Now, DISSOCIATION =√Ka/concentration =√10^-6.2/0.05 approximately =0.004 so, %=0.004100 =0.4 This* is CORRECT answer. please recheck your OPTIONS.

Answer»

Explanation:

ph=6.2

so, Ka=10^-6.2 .......... {^}denotes = power

Now, DISSOCIATION =√Ka/concentration

=√10^-6.2/0.05

approximately =0.004

so, %=0.004*100

=0.4

This is CORRECT answer.
