To solve the problem of preparing a buffer solution with a pH of 7.0 using a weak base (X) and a strong acid (HCl), we will follow these steps: ### Step 1: Determine the pKa of the base Given the base dissociation constant (Kb) of the organic base X is \( K_b = 1 \times 10^{-9} \), we can find the pKa using the relationship: \[ pK_a + pK_b = 14 \] ...
