Let $$\left[\mathrm{H}^{+}\right] = 0.001$$.

Since $$0.001 = 10^{-3}$$, we have:

$$
\mathrm{pH} = -\log_{10}\left(10^{-3}\right)
$$

Using the logarithm property $$\log_{10}\left(10^a\right) = a$$, we get:

$$
\mathrm{pH} = -(-3) = 3
$$

Thus, the pH of the solution is $$3$$.
The pH of the solution is 3.
