Given question is incomplete. The complete question is as follows.
A solution with a ph of 2 has how many more protons in it than a solution with a ph of 4?
(a) 100 times more.
(b) 5 times more.
(c) 1000 times more.
(d) 10 times more.
Explanation:
Concentration of hydrogen ion for a solution with pH = 2 will be calculated as follows.
pH =
2 =
Concentration of hydrogen ions= for a solution with pH = 4 will be calculated as follows.
pH =
4 =
Now, let us assume that volume of both the solutions is V ml.
Hence, mole of in pH = 2 will be calculated as follows.
=
Mole of in pH = 4 will be calculated as follows.
=
So,
=
= 100
Hence, mole of pH equal to 2 = 100 mole of
Thus, we can conclude that a solution with pH of 2 has 100 times more protons in it than a solution with a pH of 4.
