What are the conditions of Fajans method in Precipitation Titration?
DavidJuma
Fajans' method makes use of two facts regarding adorption effects on precipitates of a colloidal or semicolloidal state
1. finely divided precipitates tend to adsorb o their surface ions present in the solution. by doing so, the particles become electrically charged.
2. a preciptate tend to adsorb ions common to itself. thus, a precipitate of AgCl tend to adsorb Ag/Cl- in preference to forgeign ions like NO3 and Na.
Futhermore, the adsorption indicator used should not be too weakly or too strongly adsorbed by the precipitate. Otherwise, false endpoints could be observed.

Which type of the analysis the titration is?
Titration is a method of chemical analysis; for example: - volumetry - potentiometric titration - amperometric titration - radiometric titration - Karl Fisher titration - spectrophotometric titaration - viscosimetric titration and other methods
Advantages of conductometric titration?
1. this method can be used with very diluted solutions=2. this method can be used with colored or turbid solutions in which end point can not== be seen by eye==3. this method can be used in which there is no suitable indicator==4.has many applications , i.e. it can be used for acid base , redox ,precipitation, or complex titrations=

Can we Use fajans method to determined the exact concentation of a approximate 0.01 M hcl solution?
No. Fajans method relies on the naked eye, which is not as precise as analytical instruments.

Advantages of conductometric titration over volumetric method?
'Conductometric' IS a special case of volumetric analysis, it's the way of measuring the endpoint of titration. An other method is 'potentiometric' by measurement of pH.
What are the steps of the winkler method in order?
Winkler Method is a classical method(titration method) for determine the dissolved oxygen(BOD).
What is titration solution?
Titration is a common laboratory method of quantitative chemical analysis that is used to determine the unknown cocncentration of a known reactant. The word "titration" comes from the Latin word titulus, meaning inscription or title. The French word titre, also from this origin, means rank. Titration, by definition, is the determination of rank or concentration of a solution with respect to water with a pH of 7 (which is the pH of pure H2O under standard conditions).
What is the equation of titration with methyl orange?
The equation of titration with methyl orange is C14H14N3NaO3S. Methyl orange is a pH indicator that is often used in titration, which is a laboratory method of quantitative chemical analysis.
What is the role of nitric acid in the estimation of aluminium by titration method?
Eliminate any other unwanted reactant(s), that may interfere with the titration.
