Acid-Base Titrations and pH Curves Flashcards
1
Q
What is a titration?
A
- Procedure for carrying out a chemical reaction between 2 solutions
2
Q
Why is a titration useful?
A
For measuring the pH at various points throughout the reaction
3
Q
End point
A
- When indicator changes color
- End point comes before equivalence point
4
Q
Titration curve
A
A graph of the pH as a function of the amount of titrant added
5
Q
What is a titrant?
A
Known concentration
6
Q
What is the analyze?
A
Unkown concentration
7
Q
Equivalence point
A
- moles of H+ = moles of OH-
- Midpoint of the vertical portion of the titration curve
8
Q
At the equivalence point, what is the pH for strong acid-base titrations?
A
7
