Question

CALCULATE THE pH
of BUFFER SOLUTION
COMPOSED OF 0.1 M WEAK BASE BOH
AND 0.2M
of
OF ITS SALT BA.
[kg = 1.8 *10^5 for the weak base]​

Answer 1

Answer:

PH for buffer solution=pkb+log([salt]/[acid])..

pkb=-logkb.

..here given kb =1.8×10^5 and [salt]=0.2 and [base]=0.1..

applying all formula

pkb=4.245

PH=4.545
