Answer:
1000 times.
Explanation:
Hello,
In this case, since the pH is defined by:
If we want to compute the concentration of hydrogen we must write:
Thus, for both the backyard soils we compute:
It means that:
It means that the concentration of hydrogen at a pH of 4 is 1000 times greater than the concentration of hydrogen at a pH of 7.
Regards.
