What is the pH of 10-9 M HCl?
Here , [H+] for acid is < 10 -7 { which is not possible }
so,
total [H+] = 10 -7 + 10 -9
= 1.01 x 10 -7
Thus, pH = - log [H+]
= 6.99
Define Bronsted Lowry acid and base.
according to Bronsted and Lowry,
Any chemical species capable of donating a proton [H+] when dissolved in water is an acid.
Any chemical species capable of accepting proton [H+], which has a lone pair of electrons to make a bond with [H+] is a base.
