How to find pH values of given M (molarity)Eg:A solution of 0.1 M NaOH

1.	How to find pH values of given M (molarity)Eg:A solution of 0.1 M NaOH solution is given. What is the pH???
Answer» Answer: = pH = - log [ $H^{+}$ ] or -log [O $H^{-}$ ] Explanation: If the molarity of a solution is given then, First write the IONISATION reaction of the Ionic COMPOUND given For example= NaOH ⇄ N $a^{+}$ + O $H^{-}$ Here O $H^{-}$ ions are being formed. So [ O $H^{-}$ ] = Molarity of NaOH Now, USE the formula- pH= -log [O $H^{-}$ ] Hope this is useful. PLEASE rate the answer.

Answer: =

pH = - log [ $H^{+}$ ] or -log [O $H^{-}$ ]

Explanation:

If the molarity of a solution is given then,

First write the IONISATION reaction of the Ionic COMPOUND given

For example=

NaOH ⇄ N $a^{+}$ + O $H^{-}$

Here O $H^{-}$ ions are being formed.

So [ O $H^{-}$ ] = Molarity of NaOH

Now, USE the formula-

pH= -log [O $H^{-}$ ]
