Answer:
The correct answer is - D) 1000x.
Explanation:
pH is a logarithmic scale, 1 reading change leads to the results in ten-fold in the
H+ concentration in acidity/basicity. The more H
+ ions found in solution, the more acidic the substance is as acids donate H
+ ions.
You can calculate the concentration of H
+ from the pH and the equation
p
H =
−
log
[
H
+
]
arrange again
[
H
+
] = 10
−
p
H
So for a pH of 8, we get [
H
+
] =
10
^−
8
For a pH of 5, we get [
H
+
]
=
10^

5
10
^−5 /10

8=
10

= 1000
