Step 1

1 of 2The $pH$ of a solution is equal to:

$\begin{aligned} pH=-\log(H_3O^+) \end{aligned}$

Then with $pH=3.4$, the solution is:

$\begin{aligned} pH&=-\log(H_3O^+)\\ 3.4&=-\log(H_3O^+) \\ -3.4&=\log(H_3O^+)\to \boxed{\text{Take exponential form}}\\ 10^{-3.4}&=H_3O^+\\ H_3O^+ &\approx 0.0003981\\ H_3O^+ &\approx4 \cdot 10^{-3} \end{aligned}$
