Chapter 16 Acid Base Equilibrium Arrheniusdefinition Acids Any The molar concentrations of the acid and its conjugate base are approximately equal ph = pka log([base] [acid]) log([base] [acid]) =~ 0 ph =~ pk a example prepare a phosphate buffer solution with a ph of about 7 solution the concentration of the acid should be roughly equal to the concentration of its conjugate base. 16.10: acid base behavior and chemical structure. inductive effects and charge delocalization significantly influence the acidity or basicity of a compound. the acid–base strength of a molecule depends strongly on its structure. the weaker the a–h or b–h bond, the more likely it is to dissociate to form an h h ion.

Acids and bases have been defined differently by three sets of theories. one is the arrhenius definition, which revolves around the idea that acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h ) ions while bases produce hydroxide (oh ) ions in solution.
