Weak Electrolytes and Buffers Peter A Stewart † 5.1 IntroductIon Weak electrolytes affect the acid-base behavior of aqueous solutions in more complicated ways than strong ions do because they introduce additional equilibria involving H+ or OH-. This shows that weak electrolytes behave differently than strong electrolytes and do not follow the Onsager model. 0000009183 00000 n 5 g each NaCl 58.44g/mol, EG 62.07 g/mol, glucose 180 g/mol. 0000006298 00000 n x�b```b``�``e`bd@ A6 da��� ����v;�a Common examples are acids produced by dissolving molecules such as HCl in water. monochromator and detector) for single and double beam instrument; Basic principle of quantitative analysis: estimation of metal ions from aqueous solution, geometrical isomers, keto-enol tautomers.
