You measure the pH of your backyard soil and find it is 7. You measure the pH of your friend's backyard soil and find it is 4. H
olchik [2.2K]

Answer:

1000 times.

Explanation:

Hello,

In this case, since the pH is defined by:

pH=-log([H^+])

If we want to compute the concentration of hydrogen we must write:

[H^+]=10^{-pH}

Thus, for both the backyard soils we compute:

[H^+]_{pH=7}=10^{-7}=1x10^{-7}M

[H^+]_{pH=4}=10^{-4}=1x10^{-4}M

It means that:

\frac{[H^+]_{pH=4}}{[H^+]_{pH=7}} =\frac{1x10^{-4}M}{1x10^{-7}M}\\ \\\frac{[H^+]_{pH=4}}{[H^+]_{pH=7}}=1000

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.
