Identify the substances P, Q and R in each case based on the information given below:
The salt P turns yellow on dissolving in water and gives a reddish brown precipitate with sodium hydroxide solution.

Identify the substance 'R' based on the information given below: The pale green solid 'R' turns reddish brown on heating. Its aqueous solution gives a white precipitate with barium chloride solution. The precipitate is insoluble in mineral acids.

Identify the substance R based on the information given below: The pale green solid R turns reddish brown on heating. Its aqueous solution gives a white precipitate with barium chloride solution. The precipitate is insoluble in mineral acids.

Identify the substance Q based on the information given below: The white crystalline solid Q is soluble in water. It liberates a pungent smelling gas when heated with sodium hydroxide solution.

Identify the cations in each of the following case : NaOH solution when added to the Solution (A) gives a reddish brown precipitate

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.

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.

Identify the cations in each of the following cases: i] NaOH solution when added to the solution 'A' - gives a reddish brown precipitate. ii] NH_4OH solution when added to the solution 'B' - gives a white ppt which does not dissolve in excess. jii] NaOH solution when added to the solution 'C' - gives a white ppt which is insoluble in excess.

From the list of substances given- Amonium sulphate, Lead carbonate, Copper nitrate, Ferrous sulphate- State a solution of the compound which gives a dirty green precipitate with sodium hydroxide.

Identify the cation in each of the following case Sodium hydroxide solution when added to the solution 'A' gives reddish brown precipitate.

Salts P, Q,R,S,T,U and V undergo reactions (i) to (vii) respectively. Identify the cation present in these salts on the basis of these reactions. Tabulate your answer in the formate given below. (i) When the salt Pis heated with sodium hydroxide solution a vigorous reaction takes place and a colourless gas is evolved with a pungent and suffocating smell that brings tears in our eyes. The evolved gas gives dense white fumes with a moist glass rod depped with hydrochloric acid. (ii) Addition of sodium hydroxide solution to a solution of salt Q gives a thick white precipitae which is soluble in excess of sodium hydroxide solution to form a clear solution. (iii) Addition of ammonium hydroxide solution to a solution of salt R gives a dark blue precipitate which is soluble is excess of ammonium hydroxide solution to form an intense deep blue solution. (iv) Addition of ammonium hydroxide solution to a solution of 5 gives a dirty green [bottle green] precipitate which is insoluble even in the excess of ammonium hydroxide solution. (v) Addition of ammonium hydroxide solution to a solution of T gives a reddish brown (rust precipitate] precipitate which is insoluble even in the excess of ammonium hydroxide solution. (vi) Addition of ammonium hydroxide solution to a solution of V gives a geletaneous white precipitate which is soluble in excess of ammonium hydroxide solution to form a clear solution. (vii) Addition of ammonium hydroxide solution to a solution of V gives no precipitate but it gives a chalky white precipitate with sodium hydroxide solution which is insoluble even in the excess of sodium hydroxide solution.
