Calculate pH of the solution which is 10...

Calculate `pH` of the solution which is `10^(-1)M` in `HCl` & `10^(-3)M` in `CH_(3)COOH[K_(a)=2xx10^(-5)]`.Also calculate `[H^(+)]` form `CH_(3)COOH`.

AI Generated Solution

To solve the problem, we will calculate the pH of a solution that is \(10^{-1} \, \text{M}\) in HCl and \(10^{-3} \, \text{M}\) in acetic acid (\(CH_3COOH\)) with a dissociation constant \(K_a = 2 \times 10^{-5}\). We will also find the concentration of \([H^+]\) from acetic acid. ### Step 1: Calculate \([H^+]\) from HCl HCl is a strong acid and completely dissociates in solution. Therefore, the concentration of \([H^+]\) from HCl is equal to its concentration. \[ [H^+]_{HCl} = 10^{-1} \, \text{M} \] ...
