$\begin{aligned} & H^{+}=\sqrt{K \cdot C} \ & \sqrt{K_1 C_1}=\sqrt{K_2 C_2} \ & K_1 C_1=k_2 C_2 \ & 1. 8 \times 10^{-4} \times 0.001=1.8 \times 10^{-5} \times C_2 \ & C_2=\frac{10^{-7}}{10^{-5}}=10^{-2} \ &=0.01\end{aligned}$ .

At a certain temperature the dissociation constants of formic acid and acetic acid are $1.8 \times 10^{-4}$…
