Strong-Strong Titrations
Experiment 1: 45.0 mL of 0.125 M HBr is being titrated with 0.375 M NaOH.
C. Point C: 15.0 mL of the titrant has been added.
1. How many moles of HBr are in your initial sample?
2. How many moles of H3O+are in the initial sample?
3. How many moles of NaOH have been added?
4. How many moles of OH–have been added?
5. How many moles of H2O have been formed from neutralization?
(HINT:Is H3O+or OH–the limiting reactant?)
6. What is the pH of the solution now?
7. This point in the titration is called the: the __________________ point
D. Point D: 25.0 mL of the titrant has been added.
1. How many moles of HBr are in your initial sample?
2. How many moles of H3O+are in the initial sample?
3. How many moles of NaOH have been added?
4. How many moles of OH–have been added?
5. How many moles of H2O have been formed from neutralization?
(HINT:Is H3O+or OH–the limiting reactant?)
6. How many moles of OH–are left over?
7. What is the total volume of the solution after the 25.0 mL addition?
8. What is the concentration of the OH–in the solution now?
9. What is the pOH of the solution now?
10. What is the pH of the solution now?
