Web1 nov. 2024 · Step 1: choosing the conjugate acid-base pair. First, we must decide on the pH before choosing the conjugate acid-base pair. For example, imagine that we need a buffer solution of pH 6.3. Then it follows that we must choose an acid component with a pK a close to 6.3. Since pK a = -logK a, then it follows that K a = 10 -6.3 = 5.01 x 10 -7.
