When a weak acid (HA) is titrated with NaOH (a strong base), (a) what species are present in the weak acid solution before the titration is started? (b) what species is/are decreasing during the titration? (c) what species is/are increasing during the titration? (d) what species is/are not involved in the reaction? (e) what is meant by the equivalence point? (f) what important species concentration increases after the equivalence point?

How do you calculate the sample mean of the differences? How do you know which inequality symbol (less than or greater than) to use when setting up your claim? (I.e. When do you test if the difference between the matched pair data is less than zero? When is the difference greater than zero? Which distribution is used for testing a claim about dependent samples?

How do you know that HNO3 dissociates into H+ and NO3- making it an acid?

How to tell whether a substance is an acid or a base depending on its chemical formula. I know that it depends on how it dissociates; a chemical is an acid if it dissociates into a H+ and a base if it dissociates into a OH-. But how do you know what it dissociates into? How do you know that HNO3 dissociates into H+ and NO3- making it an acid? How do you know that CH3NH2 is the base and...
