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-]?
