Ionic strength effect on ph
WebFirstly, liquid junction potentials may not be independent of pH. Secondly, the high ionic strength of concentrated solutions can affect the electrode potentials. At high pH the glass electrode may be affected by "alkaline error", because the electrode becomes sensitive to the concentration of cations such as Na + and K + in the solution. Web25 feb. 2024 · where [] denotes concentration and pKa = − log Ka and pH = − log H+. pKa is a measure of the strength of acids and bases; the stronger the base, the higher the pKa. The ionic strength μ is the contribution of the total number of ions present in solution to the activity coefficient.
