What is precipitation titration in chemistry?
It is a titrimetric method which involves the formation of precipitates during the experiment of titration.
The titrant reacts with the analyte and forms an insoluble substance..
What is the aim of Argentometric titration?
In analytical chemistry, argentometry is a type of titration involving the silver(I) ion. Typically, it is used to determine the amount of chloride present in a sample. The sample solution is titrated against a solution of silver nitrate of known concentration.
What is end point in titration?
end point: the point during a titration when an indicator shows that the amount of reactant necessary for a complete reaction has been added to a solution.
Which indicator is Mohr’s method?
chromate ionsIn Mohr’s method, chromate ions are used as the indicator.
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.
Which indicator is not used in acid base titration?
The titration shows the end point lies between pH 8 and 10. This is due to the hydrolysis of sodium acetate formed. Hence phenolphthalein is a suitable indicator as its pH range is 8-9.8. However, methyl orange is not suitable as its pH range is 3.1 to 4.5.
What precipitation means?
When we talk about precipitation, we are talking about water that is falling out of the sky, this could be rain, drizzle, snow, sleet, hail or something rarer!
Which titration is known as Argentometric titration?
The titrations with silver nitrate are known as argentometric titration. This titration is carried out for chloride, cyanide, and bromide ions.
Why precipitation titration is called Argentometric titration?
It is a type of precipitation titration which involves the use of silver ion. Symbol of silver is Ag which is taken from its latin name argentum. So, word argentometric is also taken from latin word argentum.
What is Mohr method of titration?
This method determines the chloride ion concentration of a solution by titration with silver nitrate. As the silver nitrate solution is slowly added, a precipitate of silver chloride forms. … If the solutions are acidic, the gravimetric method or Volhard’s method should be used.
Why is potassium chromate used as an indicator?
An indicator that could be used is potassium chromate(VI). Silver ions can combine with chromate(VI) ions to produce a red precipitate of silver chromate(VI). … So the sudden appearance of the red silver chromate can be used to indicate the end point of the titration.
Which indicator is used in non aqueous titration?
Crystal voiletThe important indicator used for non-aqueous titration are follow:- 1. Crystal voilet:- It is used as 0.5% solution in glacial acetic acid, it gives voilet colour in basic medium and yellowish green in acidic medium. It is most widely use for the titration of pyridine with prechloride acid.
