A certain salt X gives the reaction,When Con.`H_2SO_4` is added to a hot solution of X, white crystals of an acid Z separates out. Identify X, and Z.

Consider the reactions: Identify A, X, Y and Z

A certain salt X gives the following reactions (i) Its aqueous solution is alkaline to litmus

The product obtained when HCl or H_(2)SO_(4) is added to an aqueous solution of borax is

A certain salt X gives the following reactions (ii) It swells up to a glassy matter Y on heating

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

Give a reaction which indicates dehydration property of con. H_2SO_4

When a white crystalline compound 'X' is heated with K_(2)Cr_(2)O_(7) and concentrated H_(2)SO_(4) a red dish brown gas 'A' is evolved. On passing 'A' into caustic soda solution, a yellow coloured solution of 'B' is obtained. Neutralising the solution 'B' with acetic acid and on subsequent addition of lead acetate a yellow precipitate C is obtained. When 'X' is heated with NaOH a colourless gas is evolved and on passing this a gas into K_(2)HgI_(4) (Nessler's reagent) solution a reddish brown precipitate D is formed. Identify '(A), (B), (C), (D) and X. Write equations for the reactions involved.

A salt (A) when heated with K_2 Cr_2 O_7 and conc. H_2 SO_4 liberates a gas which is absorbed in NaOH solution. The NaOll solution turns yellow. When this solution is acidified with acetic acid and lead acetate solution is added, a yellow precipitate (B) is formed. The acid radical present in the salt is

Phenol on treatment with Br_2 in CS_2 at low temperature gives two isomeric monobromo phenols 'X' and 'Y'. But phenol on treatment with bromine water giver a white precipitate 'Z'. Identify the products 'X','Y' and 'Z'.
