Concentration of Analyte vs Concentration of Titrant
Formel
How Titration Calculations Work
Formula
C_a = (C_t × V_t × n_a) / (V_a × n_t)
Where:
At the equivalence point, moles of titrant and analyte are in stoichiometric ratio.
Lösungsbeispiel
50 mL of unknown HCl is titrated with 0.1 M NaOH; 25 mL NaOH is used to reach equivalence.
- 01C_a = (C_t × V_t × n_a) / (V_a × n_t)
- 02C_a = (0.1 × 25 × 1) / (50 × 1)
- 03C_a = 2.5 / 50
- 04C_a = 0.05 M
Häufig Gestellte Fragen
What is a titration?
A titration is a technique where a solution of known concentration (titrant) is added to a solution of unknown concentration (analyte) until the reaction reaches the equivalence point.
What is the equivalence point?
The equivalence point is when the moles of titrant exactly react with the moles of analyte in stoichiometric proportion.
What indicators are used?
Common indicators include phenolphthalein (colorless to pink, pH 8-10) and methyl orange (red to yellow, pH 3-4). The choice depends on the expected pH at the equivalence point.
