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 give ble colour with anhydrous `CuAO_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 ?

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

State the inference drawn from the following observations: A salt 'Y' which reacts with BaCl_2 solution to give a white precipitate insoluble in dil: HCI. State the anion in 'Y'.

A white colored inorganic salt formed by an element fo group 14 give the following reactions : a. It is soluble in water and the solution has sweet taste . b. The salt when heated gives acetone and a yellow colored residue which is used in paints . c. The solution of the salt gives a white precipitate with dil HCi which is soluble in hot water . Explain the above observations with chemical reactions involved .

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 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 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.

Sodium salt of an organic acid 'X' produces effervescence with conc. H_(2)SO_(4) . 'X' reacts with the acidified aqueous CaCl_(2) solution to give a white precipitate which decolourises acidic solution of KMnO_(4) 'X' is

(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 gases evolved in (i) are:

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) .
