What are silver salts?
Examples: silver chloride, silver fluoride, silver iodide, silver bromide, silver astatide, silver sulfide, silver nitrate etc. For silver halogenides a method of preparation is the reaction between silver nitrate and a salt containing the halogen.
What is the separation technique for Silver chloride and sodium trioxonitrate?
Silver chloride is insoluble in water; filtration is a simple method.
How do you obtain pure crystals of sodium chloride when hdyrochloric acid is added to sodium hydroxide?
Sodium chloride is soluble in water, but zinc carbonate is not. Here is a procedure based on that simple difference in solubility. 1. Place the mixture in water and stir. The sodium chloride will dissolve. 2. Pour it through a filter. The insoluble zinc carbonate will remain on the filter, but the sodium chloride solution will pass through the filter. 3. Allow the water to evaporate from the sodium chloride solution. You are left with pure solid sodium chloride.
What is cellulose filler?
The most traditional method of filling cracks and holes on a surface before decorating.
What is Lukas's reagent?
Lucas' reagent is a solution of anhydrous zinc chloride in concentrated hydrochloric acid used to classify low molecular weights of alchohols. In 1930, this test became the standard method in qualitative organic chemistry.
What are the limits for determination of chloride by the Mohr method?
1- done only in neutral medium. 2- all the cations which give insolublld be chromate must be absent or removed before titration. 3-titration of Ag+ with Cl- is not feasible. 4- not suitable for I- and SCN-
What any other method that can analyze chloride ion in seawater?
- Potentiometric titration with silver nitrate (AgNO3) - Titration (manual) with silver nitrate (AgNO3) or mercuric thiocyanate - Chronopotentiometry - Using ISE (Ion Selective Electrode) for Cl-
Why is blank titration necessary in the mohr method?
AS silver ions first react with Cloride ions in the sample(equivalence point) and when all the chloride ions are consumed we have to add more silver nitrate solution to increase its concentration to a level where it can precipitate chromate ions as silver chromate precipites (reddish brown ppts) this is the end point . so remove this error of equivalence point detection we take the same volume of indicator (chromate solution) in a flask labelled blank and add water into this flask (the same volume as that of sample solution) and then titrate this blank labelled flask with standard silver nitrate solution and note the volume of titrant consumed (blank volume),then calculations for real equivalence point can be made as: equivalence point=(end point)-(blank volume)
Why is back titration required in the volhard method?
This method uses a back titration with potassium thiocyanate to determine the concentration of chloride ions in a solution.Before the titration an excess volume of a standardized silver nitrate solution is added to the solution containing chloride ions, forming a precipitate of silver chloride (AgCl). The term 'excess' is used as the moles of silver nitrate added are known to exceed the moles of sodium chloride present in the sample so that all the chloride ions present will react.Ag+ + Cl- AgCl(s) (Ksp = 1.70 × 10−10)Excess WhiteExcess of Ag+ is back titrated with SCN-.

Why is the titration method suitable for the preparation of potassium nitrate?
bcz titration is da worst method
