Answer:

H = 0.0000001

Step-by-step explanation:

The acidity is:

pH = -logH

If a substance has a pH of 7, what is its H value?

This means that pH = 7, we have to find h.

-\log{H} = 7

\log{H} = -7

We apply the following logarithm property:

10^{\log{a}} = a

So

10^{\log{H}} = 10^{-7}

H = 0.0000001
