How can you tell the difference between KI and KBr?

KBr – Colorless crystals or white granules or powder, soluble in water, Sparingly soluble in ethanol. KI – white solid, soluble in water, Slightly soluble in ethanol.

How can you identify the chloride bromide and iodide ions from the given salts?

Answer

1. If Chloride ions are present, we will observe a white precipitate.
2. If Bromide ions are present a light yellow precipitate will be observed.
3. If Iodide ions are present a yellow precipitate will be observed.

How can you detect chloride ion in a salt sample discuss in details with chemical reaction?

The test for chloride ions described here is based on precipitation of an insoluble chloride salt. When a few drops of a silver nitrate solution are added to a slightly acidic aqueous solution that contains chloride ions, a white precipitate of silver chloride will form.

How can you tell the difference between bromide and iodide?

Chlorine, bromine and iodine are halogens. Their ions are called halide ions, eg chloride, Cl –….Testing for halide ions

1. chloride ions give a white precipitate of silver chloride.
2. bromide ions give a cream precipitate of silver bromide.
3. iodide ions give a yellow precipitate of silver iodide.

How can you distinguish between sodium chloride and sodium bromide?

Method 1: identify aqueous NaCl from aqueous KCl from aqueous silver nitrate

• With silver nitrate, NaCl and NaBr gives AgCl and AgBr precipitates respectively.
• AgCl is not soluble in water and form a white color precipitate.
• AgBr is a pale yellow color insoluble precipitate in water.

How do you test for sulfate ions?

Testing for sulfate ions Sulfate ions in solution, SO 4 2 -, are detected using barium chloride solution. The test solution is acidified using a few drops of dilute hydrochloric acid, and then a few drops of barium chloride solution are added. A white precipitate of barium sulfate forms if sulfate ions are present.

How do you test for carbonate ions?

Carbonate ions, CO 3 2-, are detected using a dilute acid . Bubbles are given off when an acid, usually dilute hydrochloric acid, is added to the test compound . The bubbles are caused by carbon dioxide. Limewater is used to confirm that the gas is carbon dioxide.

How do you test for bromide ions using chlorine?

When chlorine (as a gas or dissolved in water) is added to sodium bromide solution, the chlorine takes the place of the bromine. Because chlorine is more reactive than bromine, it displaces bromine from sodium bromide. The solution turns brown. This brown colour is the displaced bromine.

How would you test for the presence of chloride ions in solution of sodium chloride?

The test solution is acidified using a few drops of dilute nitric acid, and then a few drops of silver nitrate solution are added. Different coloured silver halide precipitates form, depending on the halide ions present: chloride ions give a white precipitate of silver chloride.

How can you tell the difference between sodium chloride and sodium iodide?

One can distinguish sodium chloride from sodium iodide by looking at the precipitate formed after adding the salts to separate silver nitrate solutions. Sodium chloride reacts with silver nitrate to form a white silver chloride precipitate, while sodium iodide reacts with silver nitrate to form a yellow silver iodide precipitate.

What happens when you mix sodium chloride and silver nitrate?

Sodium chloride reacts with silver nitrate to form a white silver chloride precipitate, while sodium iodide reacts with silver nitrate to form a yellow silver iodide precipitate. Another way to distinguish sodium chloride from sodium iodide is by adding the salts to concentrated sulfuric acid.

How to test chloride ion in the presence of bromide ion?

We can do concentrated sulfuric acid and manganeese dioxide to test chloride ion in the presence of bromide ion. Here how it does. Add concentrated sulfuric acid and heat the mixture. You can see a vapour of Br 2 in red brown colour.

How to prepare silver nitrate precipitate from barium chloride?

Add a few drops of dilute hydrochloric acid, then a few drops of barium chloride solution. A white precipitate forms if sulfate ions are present. Add a few drops of dilute nitric acid, then a few drops of silver nitrate solution. Observe and record the colour of any precipitate formed. Record the results in a suitable table.
