The pH of a solution of a strong monoprotic acid is lower than the pH of an equal concentration of a weak monoprotic acid, yet equal volumes of both require the same volume of basic titrant to reach the equivalence point. Explain why.

Describe how you expect the pH of your weak acid solution to change when strong base is slowly added to it. When making this description, assume you have a monoprotic acid. Comment on how much the pH changes at the beginning of the titration, when about half the acid has been titrated, and when nearly all the acid has been titrated. Use the terms half-equivalence point and equivalence point in this discussion. How would the titration curve of a diprotic...

POST-LABORATORY QUESTIONS 1. Explain how it is possible for the concentration of acetic acid to be higher than that of hydrochloric acid in solutions that have the same H3O ion concentration (same pH)? Remember, both acids ionize to form only one mole of hydronium ions per mole of acid that ionizes. 2. Do you think it is accurate to consider the titration end point as the same as the "equivalence point"? Why? How do you know that an indicator's color...

Consider the titration of a weak acid with a strong base. Which statement below is true regarding the equivalence point in this titration? It occurs at a pH less than 7.0 because an acidic salt is formed. h It occurs at a pH greater than 7.0 because an acidic salt is formed. It occurs at a pH 7.0 because the acid has been neutralized It occurs at a pH greater than 7.0 because a basic salt is formed e It...
