Why copper nitrate is blue?

When the solution is diluted with water, water molecules displace the nitrate ions in the coordinate sites around the copper ions, causing the solution to change to a blue color.

What is the Colour of lead nitrate?

white
Lead nitrate is a white crystalline solid. The material is soluble in water.

What is the Colour of potassium nitrate solution?

White
Potassium Nitrate Solution Properties (Theoretical)

When copper turnings are added to silver nitrate solution a blue Coloured solution is formed after sometime it is because copper?

When copper turnings are added to silver nitrate solution, a blue coloured solution is formed after some time. It is because of copper. oxidises silver from the solution.

What is the colour of no2 formed when lead nitrate is heated?

brown
Where lead(II) nitrate undergo decomposition reaction to give yellow colour lead (II) oxide, colourless gas of oxygen and brown colour nitrogen dioxide.

Is potassium nitrate the same as sodium nitrate?

Sodium nitrate is the chemical compound with the formula NaNO3. and molecular mass of 84.9947 g/mol. This salt, also known as “Chile saltpeter” (to distinguish it from ordinary saltpeter, potassium nitrate), is a white solid which is very soluble in water.

What is the Colour of sodium nitrate?

Sodium nitrate appears as a white crystalline solid.

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?

Nickel ion solution and ammonia solution reaction When concentrated ammonia solution is added to the aqueous green colour Ni 2+ solution (Ni (NO 3) 2 or NiCl 2), blue colour hexaamminenickel (ii) ion ([Ni (NH3)6]2+) is given.

Is nickel nitrate soluble in ammonia solution?

Nickel nitrate and nickel chloride are soluble compounds in water. Nickel ion solution and ammonia solution reaction When concentrated ammonia solution is added to the aqueous green colour Ni 2+ solution (Ni (NO 3) 2 or NiCl 2), blue colour hexaamminenickel (ii) ion ([Ni (NH3)6]2+) is given.

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.
