What is OS How will you prepared in chemistry?

In salt analysis. Note: The original solution (OS) of the salt can be prepared by mixing a small amount of the inorganic salt with water and acid.

What is OS in chemistry?

osmium (Os), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table and the densest naturally occurring element. A gray-white metal, osmium is very hard, brittle, and difficult to work, even at high temperatures.

How do you prepare a salt analysis solution?

dissolve 169 g of the salt in 1 liter of solution (3M). a saturated aqueous solution is prepared by shaking 35g or 11ml liquid bromine with water. Add more bromine if necessary to a slight excess.

What is original solution and how it is prepared?

Original solution is the solution of a mixture in the suitable solvent. The solvent can be water, dil. HCl, conc. HNO whereas a salt solution is the solution of a single salt in water. It can be either basic or acidic depending upon the ions present in the salt.

What is a salt analysis?

Salt analysis is the quantitative and qualitative analysis of cations and anions present in a given inorganic salt. The salt analysis involves a series of steps that help in identifying a salt and its constituent ions.

How do you test for salt in chemistry?

The basic testing procedure for identifying a salt is as follows.

1. Appearance of compound. The compound will most likely be in solid form.
2. Heating effect.
3. Flame test.
4. Solubility in water.
5. Reaction with nitric acid.
6. Reaction with sodium hydroxide.
7. Reaction with ammonia.
8. Reaction with hydrochloric acid.

What is a full form of OS?

operating system (OS), program that manages a computer’s resources, especially the allocation of those resources among other programs. Typical resources include the central processing unit (CPU), computer memory, file storage, input/output (I/O) devices, and network connections.

What element is OS on the periodic table?

76
Osmium/Atomic number

What is salt analysis chemistry?

How do you identify a salt in chemistry?

There is a certain basic procedure to identify a salt that can be followed.

1. Look at the Appearance of the Compound.
2. Check the Effect of Heating.
3. Conduct a Flame Test.
4. Test Its Reaction with Hydrochloric Acid.
5. Note Its Solubility in Water.
6. Sieve analysis.
7. Moisture analysis.

What is original solution in salt analysis?

Transparent, aqueous solution of salt is known as original solution and it is prepared by dissolving slat/mixture in suitable solvent.

What is original solution in salt?

Original solution is a homogeneous mixture, which is made up of solute and solvent. In original solution solute is present as dissolved salts. where as salt solution is also a homogeneous mixture which is made by adding more quantity of solute.

What is the most common salt used in Salt analysis?

Finally, certain salts are very common in salt analysis examinations. For example, the most common salt containing the bromide ion (Br –) is NH 4 Br and the most common salt containing the calcium cation (Ca 2+) is CaCl 2.

What are the preliminary tests for cations in Salt analysis?

In salt analysis. preliminary tests for cations must be conducted in order to check for the presence of different cations in the inorganic salt. This is done in a manner that is similar to the preliminary tests for anions. Note that some cation groups (such as group 0 and group 6 cations) do not have any preliminary tests.

Why does salt have a strong ordered structure?

This attraction between ions means that a compound with ionic bonds will have a strong, ordered structure. Salts often form a crystal structure or crystal lattice, a highly ordered formation of molecules. This is why we get crystals of salt on our fries.

How do you test for Group 3 anions in salt water?

Experiment: Take a small chunk of the salt in a test tube and add a few drops of concentrated H 2 SO 4 (sulfuric acid) to it (If nothing happens, move on to preliminary test for group 2 anions). The sulphate and phosphate ions (group 3 anions) do not have any preliminary tests.
