Lead hydroxide precipitates are ……………………. in water.

When potassium iodide solution is added to lead acetate solution, a red precipitate is formed. ………………….

Na_2CrO_4 on treatment with lead acetate gives a precipitate. This dried precipitate is used as a pigment for road signs and markings . The solid is known as:

To a solution of a substance gradual addition of ammonium hydroxide result in a black precipitate which does not dissolve in excess of NH_(4)OH however when HCI is added to the original solution a white precipitate is formed .The solution containe

Which of the following alkaline earth metal hydroxides is the least soluble in water?

Which of the following alkaline earth metal hydroxides is the least soluble in water?

Explain the following: (i). Copper hydroxide is soluble in ammonium hydroxide but not in sodium hydroxide. (ii). A dark blue precipitate is formed when sodium hydroxide solution is added to copper sulphate solution. The precipitate darkens on heating.

The colour of precipitate obtained when ammonium hydroxide is added to ferric chloride is ……………………

Statement-1 : Sodium meta aluminate on boiling with ammonium chloride produces white gelatinous precipitate. Statement-2 :Aluminium hydroxide is formed which is not soluble in water

Sodium hydroxide solutions to the solutions containing the ions mentioned in list x list y gives the detail of the precipitate match the ions their coloured precipitates

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.
