Text p k_ a pk a of acetic acid
Web[c] [2] As a simple example for a weak acid with K a = 10 -5, log K a is the exponent which is -5, so that pK a = 5. And for acetic acid with K a = 1.8 x 10 -5, pK a is close to 5. A higher K a corresponds to a stronger acid which is more dissociated at equilibrium. For the more convenient logarithmic scale, a lower pK a means a stronger acid.

Web7 Apr 2024 · The peak potential (E p) of p -Ap, resulting from modified SPCE, is consistent at 0.09 volts. There are two stages of p -AP oxidation ( Figure 2 ): the first was from p -AP to quinonimine and continued to quinone [ 41, 42 ]. In the second stage of oxidation, a broad peak was not detected in the modified SPCE.
