Ionization Constants of Organic Acids - Michigan State University

WebThe Ka value for most bases ranges from 10⁻² to 10⁻¹⁴; i.e., pKa is 2 to 14. The ion constant for water is represented as Kw, which connects Kb and Ka as Kw = Kb x Ka Hence, the Ka Kb equation may be written as pKa + pKb = 14. CONCLUSION The strengths of acids and bases can be measured based on how they dissociate in water. key account manager healthcare
