What is the importance of titration value?
Titration Explained The purpose of titration is to determine an unknown concentration in a sample using an analytical method.
How do you calculate precipitation titration?
The results of a precipitation titration experiment can be used to determine the concentration of halide ions in water samples as shown in the steps below:
- For the precipitation reaction: Ag+(aq) + X-(aq) → AgX(s)
- Volume of AgNO3(aq) added is recorded (titre) and the average titre calculated (in L).
What is the principle of precipitation titration?
Principle of Precipitation Titration The main principle of the precipitation titrations is that the quantity of the added precipitating reagent or precipitant is equivalent to the substance being precipitated.
How is precipitation titration used in industry?
Precipitation titration is used in many industries. The most important applications are halide (especially chloride) and silver determinations. Some precipitation titrations are also acid-base titrations in the plating bath industry.
Why is back titration used?
A back titration is used when the molar concentration of an excess reactant is known, but the need exists to determine the strength or concentration of an analyte. When direct titration endpoint would be hard to discern (e.g., weak acid and weak base titration) When the reaction occurs very slowly.
What is precipitation titration with example?
Precipitation Titration Example Example – To determine the concentration of chloride ion in a certain solution we can titrate this solution with silver nitrate solution (whose concentration is known). The chemical reaction occurs as follows: Ag+(aq) + Cl–(aq)→ AgCl(s).
Which indicator is used in precipitation titration?
Potassium chromate is used as indicator. At the end point, when all chloride ions are consumed by silver ion, reddish brown colored precipitate is formed by reaction of silver ion and chromate ion.
Which titration is EDTA mainly used?
Complexometric titration with EDTA is used for the determination of any metal ion with the exception of alakaline metals.
What is back titration method?
A back titration is a titration method where the concentration of an analyte is determined by reacting it with a known amount of excess reagent whereas a direct titration directly measures the concentration of the unknown compound. A back titration may also be called an indirect titration.
