Explain Buffer solution.
यदि किसी विलयन का pH = 12 है, तब इस विलयन
OH आयन की सान्द्रता की गणना कीजिए।
If pH value of a solution is 12 then calcula
concentration of OH ion.
​

Answer 1

Answer:

The solution which resists any change in pH even when small amount of acid or base is added to it.

If pH is 12

pOH=?

pKw= pH + pOH

14 = 12 + pOH

pOH = 10^2

pOH = - log (OH-)

(OH) = 2
