Burning magnesium ribbon is taken in gas P when it form a salt R. The salt R dissolves in water and gives curdy white precipitate with silver nitrate solution. This precipitate is soluble in excess of ammonium hydroxide solution. Name the gas P and salt R. State the chemical reaction between P and magnesium

Identify the anion present in the following compound : When a solution of compound Y is treated with silver nitrate solution a white precipitate is obtained which is soluble in excess of ammonium hydroxide solution.

Identify the acid which matches the following description The acid on mixing with silver nitrate solution produces a white precipitate which is soluble in excess ammonium hydroxide.

Identify the acid which matches the following description (i) to (v): The acid on mixing with silver nitrate solution produces a white precipitate which is soluble in excess ammonium hydroxide.

Identify the salts P from the observations given below: On performing the flame test salt P produces a lilac coloured flame and its solution gives a white precipitate with silver nitrate solution, which is soluble in Ammonium hydroxide solution.

A metal salt solution gives a yellow precipitate with silver nitrate.The precipitate dissolves in dilute nitric acid as well as in dilute ammonia solution.The solution contains :

A white solid P, on strong heating, decomposes to give reddish brown gas R and a residue Q. The residue R is yellow when hot and white when cold. The solution of white solid P in water gives white precipitate S, with concentrated sodium hydroxide. The white precipitate S dissolves in excess of sodium hydroxide solution to form colourless solution. Another sample of the solid P in water is mixed with ferrous sulphate solution and then to this solution are added a few drops of conc. sulphuric acid. A brown ring is formed at the junction of liquids. Answer the following questions: Name the salt formed when S dissolves in excess of sodium hydroxide.

Identify the salts P & Q from the observations given below: i] On performing the flame test salt P produces a lilac coloured flame & its solution gives a white precipitate with silver nitrate solution, which is soluble in ammonium hydroxide solution. ii] When dilute HCl is added to a salt Q, a brisk effervescence is produced and the gas turns lime water milky. When NH_4 OH solution is added to the above mixture [after adding dilute HCI], it produces a white precipitate which is soluble in excess NH_4OH solution.
