IntermediateMCQMathematical22k
A student prepares a buffer solution using a weak monoprotic acid, \(\text{HA}\) (\(K_a = 1.0 \times 10^{-5}\)), and its conjugate base, \(\text{A}^-\). The \(\text{pH}\) of the final solution is adjusted to \(6.00\) at \(25\ ^\circ\text{C}\). Based on this information, which of the following is closest to the percentage of the acid species present in the deprotonated form, \(\text{A}^-\)?
