2 cards from this section. Quick, good the night before a test.
What is a polyprotic acid?
Think of examples like citric acid.
Explain the term equivalence point.
It's where the reaction is complete.
What characterizes a polyprotic acid?
Look for acids that have more than one H⁺ ion.
True or False: The second equivalence point of a diprotic acid titration occurs after all H⁺ ions have reacted.
Think about when reaction completion happens.
A diprotic acid solution with a concentration of 0.0500 M is titrated with 0.0500 M NaOH. Calculate the pH at the first equivalence point.
You might need to look up or recall the Ka values for this acid.
Explain what happens to the pH after the second equivalence point for a diprotic acid.
Consider the role of excess base after the equivalence point.
