Calculate `[H^(o+)]` and `[overset(Θ)OH]` in `10^(-3)M` solution of monobasic acid which is `4.0%` ionised. What is the `pH,K_(a)` and `pK_(b)` of the acid.

Explanation

To solve the problem step by step, we will calculate the concentrations of hydrogen ions \([H^+]\) and hydroxide ions \([OH^-]\) in a \(10^{-3} M\) solution of a monobasic acid that is \(4.0\%\) ionized. We will then find the \(pH\), \(K_a\), and \(pK_a\) of the acid.

### Step 1: Calculate the degree of dissociation (\(\alpha\))

Given that the acid is \(4.0\%\) ionized, we can express the degree of dissociation \(\alpha\) as:
\[ \alpha = \frac{4}{100} = 0.04 \]
