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
What does it mean when Qsp is more than Ksp?
The solution IS saturated (precipitate forms
Shifts Right
What is the same as a covalent bond but is when one atom provides both bonding electrons?
Coordinate Covalent Bonds
What is it called when two or more reactions share one or more reactants and products?
Coupled equilibrium
