Addition of NaOH on Zn^(2+) ion gives a white ppt. which on addition of excess of NaOH which dissolves . In this solution Zn exists in

Zinc(II) ion on reaction with NaOH first give a white precipitate which dissolves in excess of NaOH due to the formation of :

A white amorphous powder (A) when heated gives a colourless gas (B), which turns lime water milky and the residue (C) which is yellow when hot but white when cold. The residue (C) dissolves in dilute HCl and the resulting solution gives a white precipitate on addition of potassium ferrocyanide solution. (A) dissolves in dilute HCl with the evolution of a gas which is identical in all respects with (B). The solution of (A) as obtained above gives a white precipitate (D) on addition of excess of NH_(4)OH and on passing H_(2)S . Another portion of this solution gives initially a white precipitate (E) on addition of NaOH which dissolves in excess of it. Compounds (A) to (E) are identified as:

A white amorphous A on heating yields a colourless, non-combustible gas B a solid C .The latter compound assumes a yellow colour on heating and changes to white on cooling C dissolve in dilute hydrochloric acid and the resulting solution gives a white precipitate with K_(4)Fe(CN)_(6) solution .A dissolve in dilute HCI with the evolution of gas , which is identical in all respect B turns lime milky , but the milkiness disuppears with the contimous passage of gas solution of A as obtained above gives a white precipitate D on the addition of excess of NH_(4)OH and passing H_(2)S another portion of the solution gives initialy a white precipitate E on the addition of NaOH solution , which dissolves on further addition of base , identify the compounds A,B,C,D and E

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) .

A mixture of two white substances was dissolved in water.On passing Cl_2 gas through the solution a deep brown colour is developed. Addition of BaCl_2 solution to the original solution gives a white precipitate.Addition of a large amount of NaOH solution to the original solution gives a white precipitate, whose suspension in water is used as an antacid.The mixture gives golden yellow colour flame. The mixture contains :
