1. Titrations

2. Titrations
Gradual addition of one solution to another to determine concentration of acid or base
Neutralization reaction
Acid + Base→ H2O + salt
Use standard solution in titration
Standardized by titrating with known amount of reactant

3. Preforming Titration
Use burets to deliver known amount of standard solution to unknown solution
Indicator is chosen to show ∆ pH
Reaction is complete at the equivalence point
Point where acid has neutralized base
End point is where color change occurs
Indicator should be chosen well so equivalence point = endpoint

6. M1V1=M2V2
A student titrates mL HCl sol’n of unknown concentration with mL of M NaOH to reach the equivalence point. What is the concentration of the HCl sol’n in moles/L (M)?

7. If 29. 5mL of 0. 150 M HCl neutralizes 25. 0 mL basic sol’n
If 29.5mL of M HCl neutralizes 25.0 mL basic sol’n. What is the [OH-]?
