Quiz 5 Cards (Exam 2 Notes) Flashcards
What is it called when a solution of an unknown concentration is reacted with a solution of a known concentration?
Titration
What is it called when a reaction is complete?
Endpoint
What is the term that describes things such as color changes?
Indicators
What is it called when the moles of [H3O+] equals the moles of [OH-]?
Equivalent Point
In the titration curve, what is the steepest slope that is equal to the equivalence point called?
Inflection point
For the equivalence point, what is the pH of a neutral salt?
pH=7
For the equivalence point, what is the pH of an acidic salt?
pH is less than 7
For the equivalence point, what is the pH of a basic salt?
pH is more than 7
What does the graph look like for a strong base-strong acid graph?
The graph starts with a high and constant pH level (base) then drops dramatically (the equivalent point equals 7), then levels out to a lower pH (acid)
What does the graph look like for a strong acid-strong base graph?
The graph starts with a low and constant pH level (acid), then increases dramatically (the equivalent point equals 7), then levels out to a higher pH (base)
What does the graph look like for a weak acid-strong base graph?
The graph starts with the buffering resisting pH (geared toward acid), then a steady increase (the equivalent point has a pH of more than 7), then it flattens out
What does the graph look like for a weak base-strong acid graph?
The graph starts with the buffer resisting pH (geared towards base), then a steady decrease (the equivalent point has a pH of less than 7), then it flattens out
What looks at the solubility of a compound in moles over liters?
Molar solubility
Ionic compounds with strong or weak base anions ______ solubility with _______ pH
Increase
Lower
What does it mean when Qsp is less than Ksp?
The solution is NOT saturated (precipitate does not form)
Shifts Left
