Based on the graph it is concluded that the electrolyte can easily change its pH by adding tiny amounts of strong acid/strong base in the region of ca. pH = 4–10. Calculating the equilibrium electrode potentials for oxygen and hydrogen evolution using Nernst equation, the electrochemical...
A newly proposed method of titrating weak acids with strong bases is applied to standardize a solution of a strong base, to graphic determination of equivalence volume of acetic acid with an error of 0.2%, to calculate the stability cons... A Ivaska - 《Talanta》 被引量: 26发表: 1974年 ...
II. pH of monoprotic dilute weak acids and bases For weak monoprotic acids, an equilibrium is established between the acid and products of dissociation: HA+H2O⇌H3O++A− The equilibrium constant is defined as: construct a system of equations using material balance and charge balance: ...
