What is the concentration, in moles/liter, of the hydrogen ion, if pH of a solution is 7?
What is the concentration, in moles/liter, of the hydrogen ion, if pH of a solution is 7?
We know that
p
H
=
−
l
o
g
[
H
+
]
Given,
p
H
=
7
So,
7
=
−
l
o
g
[
H
+
]
l
o
g
[
H
+
]
=
−
7
⟹
[
H
+
]
=
10
−
7
Hence, the hydrogen ion concentration is
10
−
7
mol L
−
1
