To solve the problem of preparing a buffer solution with a pH of 4.4 using formic acid (HCOOH) and potassium formate (HCOOK), we will follow these steps: ### Step 1: Calculate the pKa of Formic Acid The dissociation constant (Ka) of formic acid is given as \(4 \times 10^{-4}\). We can calculate the pKa using the formula: \[ pK_a = -\log(K_a) \] Substituting the value of \(K_a\): ...
