The concentration of $\text{OH}^-$ in the solution is $1.4 \times 10^{-7} \, \text{M}$. To find the concentration of $\text{H}_3\text{O}^+$, we use the water ion product, $K_w = [\text{H}_3\text{O}^+][\text{OH}^-] = 1.0 \times 10^{-14}$. Solving for $[\text{H}_3\text{O}^+]$, we get $[\text{H}_3\text{O}^+] = \frac{1.0 \times 10^{-14}}{1.4 \times 10^{-7}} = 7.1 \times 10^{-8} \, \text{M}$.
