|
Titration |
The process of finding the concentration of a solution using a second solution of unknown concentration |
|
|
Titrant |
The solution of KNOWN concentration |
|
|
Titrate |
The solution of UNKNOWN concentration |
|
|
Indicator |
Substance that changes color based on ph |
|
|
Equivalence point |
Point in the titration where solutions are stoichiometrally equivalent and the indicator changes color |
|
|
Steps for titration |
1. Clean and label burets 2. Fill each with intended solution 3. Remove air bubbles 4. Record initial concentration 5. Dispense approximately 20- 25 ml of acid 6. Add 3 drops of indicator 7. Add base till one drop causes the solution to stay pink for 30 seconds 8. Record final volume 9. Repeat for 3 trials |
|
|
How to clean a buret in titration lab |
▪Rinse 3 times with the intended solution ▪use about 10-15ml of solution and pour in at an angle ▪make sure to clean the nozzle ▪do this 3 times |
