Answers: 1
value of HEPES is 7.5 and it is a weak acid. Now, the value of 
is calculated by below formula:
:
. The hydroxide ion concentration is calculated by below formula for weak base:![[OH^{-}] =\sqrt{k^{b}\times c}](/tpl/images/0079/0018/da3b2.png)
and c in above formula:![[OH^{-}] =\sqrt{3.16\times 10^{-7}\times 0.1 M}](/tpl/images/0079/0018/43bc8.png)
from the above value.![pOH = -log[OH]](/tpl/images/0079/0018/75220.png)
in above formula:
