Document Summary
Determining which species acts as a base and which as an acid. Knowing what remains after the reaction has occurred. Also look at what remains and what has been formed. Consider 3 options: strong base + strong acid, strong base + weak acid, weak base + strong acid. When ka = 1, strong acid kb = 10-14 as ka decrease and becomes weaker, kb gets larger and becomes stronger. 17. 4 acid-base titrations limiting reactant questions: either acid or base is always in excess, except at the equivalence point (mol acid = mol base for 1:1 acid:base titration) In 3 titrations diff species are formed as ph changes: Strong acid neutral salt strong base. Weak acid buffer basic salt strong base (beaker of weak acid slowly dropping strong base into it : equiv point will come when we form basic salt. Weak base buffer acidic salt strong acid: beaker of weak base slowly dropping strong acid into it.
