As we know the
pH + pOH = 14 , if you know the concentration of thesoluton you may calculate easily pH of solution as well as pOH.
Here is formula for the determination of pH,
pH = log ( H+)
and you may put the determined value of pH in the equation of pH + pOH = 14 , and get the value of pOH.
We can reduce the pH of the soultion by adding any kind of acid, if we use acid its pH may reduce to1 or even 0, it means the concentration of Hydrogen ions will be increased.
You may detect the pH of the solution by unversal indicator paper and pH meter.

Buffer Solution, Buffer Action & Buffer Capacity.
in Inorganic Chemistry

The solution which resists to change its pH is called Buffer Solution. The resistance to change in pH on the addition of small amount of acid or base is called Buffer Action. The amount of acid or alkali required to change to produce unit change of pH in the solution is called the Buffer Capacity of the solution. Our blood is the buffer solution and its pH is 7.3 .
