To calculate the concentration of a solution using acid–base titration data. In an acid–base titration, an acid (or base) of known concentration is added to a base (or acid) of unknown concentration until the number of moles of H+ and OH- are equal, a condition called the equivalence point. Since you know the number of moles of H+ (or OH- ) that you added, you can determine the number of moles of OH- (or H+) in the unknown solution. For...

In the titration of acetic acid (CH3COOH) and sodium hydroxide (NaOH), what are the major sepcies present at the following points? a) Before any NaOH is added (at the start of the titration). b) In the buffer region. Are there any spectator ions? c) At equivalence point. What is equivalent at this point? What has been used up? Are there any spectator ions? d) Beyond equivalence point. What has been added since the equivalence point? Has anything reacted further since...
