In Rothera's test, ammonium sulfate is saturated to provide a concentrated solution that aids in the separation of ketones and aldehydes from other compounds in a mixture. Saturating the solution ensures that the test is specific to detecting the presence of ketones and aldehydes, as these compounds have a higher solubility in the saturated ammonium sulfate solution compared to other substances. This selective solubility allows for the accurate identification of the target compounds in the test sample.

What chemical test to distinguish between sodium sulphate and ammonium sulphate?
One way to distinguish between sodium sulfate and ammonium sulfate is by performing a flame test. When sodium sulfate is heated in a flame, it will produce a bright yellow flame due to the presence of sodium ions. In contrast, when ammonium sulfate is heated in a flame, it will produce no distinctive color as ammonium ions do not impart a color to the flame.
What is the principle of rotheras test?
The Rothera nitroprusside test looks for ketone bodies in urine. It is done by taking 5 mL of urine and adding ten drops of concentrated ammonia water and solid ammonium sulfate. The sample is then analyzed after 15 minutes. If the sample turns purple, then that means there is acetoacetic acid in the urine.
Why do you add hydrochloric acid to test for sulphate?
Hydrochloric acid is added to a solution being tested for sulphate ions to precipitate the sulphate as barium sulphate. This is a confirmatory test for the presence of sulphate ions in the solution because barium sulphate is insoluble and forms a white precipitate.
How can you identify Ammonium?
Ti identify ammonium ion, NaOH is added to the original solution of the ammonium salt and a paper dipped in HCl is brought to mouth of test tube. If white vapours are observed, then ammonium is present. Or Neissler's reagent(K2HgI4) can be added to the original solution of the ammonium salt. A reddish brown ppt. is observed in case of ammonium ion.
What colour flame test do sodium sulphate and potassium chloride give?
well , the colour of potassium chloride is a lilac colour :) hope this helps

What is the test for an ammonium compound?
To test for an ammonium compound, you can add sodium hydroxide solution to the compound and heat gently. If ammonia gas is produced, it confirms the presence of an ammonium compound.

Does Dilaudid and Morphine Sulphate show the same on a urine test strip?
no

What color flame test does ammonium chloride give?
NH4Cl should not have an impact on a flame thus will emit a orange/yellow glow.
How can you test a solution for the barium ions?
Acidify the given solution with a few drops of concentrated HNO3 followed by the addition of 4 mol dm-3 sulphuric acid or ammonium sulphate. A white precipitate implies that there are Barium (II) ions present in the solution. The objective of the test give above is to recognize the Barium(II) ions as the white precipitate of barium sulphate which is not soluble in most of the solvents. Adding a sulphate solution at first might cause distractions as other cations such as strontium also make white precipitates with sulphate ions. Those other precipitates dissolve in dilute nitric acid.
What is ammonium molybdate test?
The ammonium molybdate test is a qualitative analytical test used to detect the presence of phosphate ions in a sample. It involves adding ammonium molybdate reagent to the sample, resulting in the formation of a yellow precipitate if phosphate ions are present. The intensity of the yellow color can provide an indication of the concentration of phosphate ions in the sample.
What is the role of ammonium sulfate in test for presence of protein?
The ammonium sulfate denatures the protein, making it available for indicating reagents such as Biuret or Bradford
Why is barium chloride and alcohol used in the limit test for sulphates?
Barium chloride is used in the limit test for sulphates because it forms a precipitate with sulphate ions. Alcohol is added to the mixture to promote the formation of small crystals, which makes it easier to detect the presence of sulphate ions in the sample.
