Does silver react with HCl?

Silver metal does not react with dilute HCl.

Is silver nitrate soluble in HCl?

Silver, for example, will dissolve in hydrochloric acid, or HCl, to form silver chloride, or AgCl. The full dissolution of silver requires nitric acid, or HNO3, which reacts with silver to form silver nitrate, a water-soluble compound.

What color is nitrate?

The nitrate ion does not have any colour of its own. If a nitrate salt is having colour, then it should be due to the metal ion associated with it in the salt. Copper nitrate is blue, like copper sulphate , or any other copper(II) salt.

What happens when ammonia is added to NiCl2?

What is the Bayer’s test for unsaturation?

B. Bayer’s test Dissolve 25-30 mg of organic compound in 2 mL of water or acetone (free of alcohol) and add 1\% potassium permanganate solution containing equal volume of 1\% sodium carbonate solution. The discharge of the colour of more than one drop of potassium permanganate indicates the presence of unsaturation in the organic compound.
