Step 1

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

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

Then with $pH=4.8$, the solution is:

$\begin{aligned} pH&=-\log(H_3O^+)\\ 4.8&=-\log(H_3O^+) \\ -4.8&=\log(H_3O^+)\to \boxed{\text{Take exponential form}}\\ 10^{-4.8}&=H_3O^+\\ H_3O^+ &\approx 0.00001584\\ H_3O^+ &\approx 1.6 \cdot 10^{-5} \end{aligned}$
