When `Cl_(2)` reacts with cold dilute `NaOH` solution, the salt of oxyacid `X` and another salt `Z` are formed along with colourless liquid which gives blue colour with anhydrous `CuSO_(4)`, `Z` gives a white precipitate with `AgNO_(3)`. The oxidation state of chlorine in `X` is _____

Which of the gives a white precipitate with a solution of AgNO_(3) , a white precipitate with dil H_(2)SO_(4) and a green flame test ?

An aqueous solution of salt gives salt precipitate with AgNO_(3) solution as well as with dilute H_(2)SO_(4) . It may be

A white substance (A) reacts with dilute H_(2)SO_(4) to produce a colourless suffocating gas (B) and a colourless solution (C )/ The reaction of gas (B) with potassium iodate and starch solution produce a blue colour solution. Aqueous Solution of (A) gives a white precipitate with BaCl_(2) solution which is soluble in dilute HCl . Addition of aqueous NH_(3) or NaOH to (C ) produced first a precipitate which dissolves in excess of the respective reagent to poduced a clear solution. Similarly addition of excess of potassium ferrocyanide to (C ) produced a precipitate (D) which also dissolves in aqeous NaOH giving a clear solution. Identify (A),(B),(C ) and (D ). Write the equation of the reactions involved.

A metal X on heating in nitrogen gas gives Y,Y on treatment with H_(2)O gives a colourless gas which when passed through CuSO_(4) solution gives a blue colour. Y is:

A salt solution of Cd^(2+) in dilute HCl, on treatment with a solution of BaCl_(2) gives a white precipitate, which is insoluble in concentrated HNO_(3) . Anion in the salt may be :

A metal salt solution forms a yellow precipitate with potassium chromate in acetic acid, a white precipitate with dilute H_2 SO_4 but gives no precipitate with sodium chloride or iodide, it is

An inorganic compound (X) shows the following reactions : (a) It is white solid, exists as dimer and fumes in moist air. (b) It sublimes at 180^@ C and forms monomer on heating to 400^@ C . ( c) Its aqueous solution turns blue litmus red and gives a white precipitate with AgNO_(3) solution which is soluble in excess of NH_(4) OH . (d) Addition of NaOH to the solution of (A) gives a white gelatinous precipitate which is, however, soluble on excess of NaOH . Identify the compound (A) .

The solution of a chemical compound X reacts with AgNO_(3) solution to form a white precipitate of Y which dissolves in NH_(4)OH to give Z. When Z is treated with dil HNO_(3) ,Y reappears .The chemical compound X can be

(i) A white solid mixture of two salts containing a common cations in insoluble in water. It dissolves in dilute HCl producing some gases (with effervescence) that turn an acidified dichromate solution gren. After the gases are passed through the acidified dichromate solution, the emerging gas turns baryta water milky. (ii) On treatment with dilute HNO_(3) , the white solid gives a solution which does not directly give a precipitate with a BaCl_(2) solution but gives a white precipitate when warmed with H_(2)O_(2) and then treated with a BaCl_(2) solution. (iii) The solution of the mixture in dilute HCl, when treated with NH_(4)Cl,NH_(4)OH and an Na_(2)HPO_(4) solution, gives a white precipitate. Q. The white precipitate obtained in (ii) indicates the presence of a:
