How do you account for the following observations ?
When concentrated sulphuric acid is added to an inorganic mixture containing chloride, we get colourless pungent smelling gas HCI, but if the mixture contains bromide then we get red vapour of bromine. Why?

AI Generated Solution

To account for the observations when concentrated sulfuric acid is added to an inorganic mixture containing chloride or bromide, we can analyze the reactions that occur with each halide. ### Step-by-Step Solution: 1. **Identify the Halides**: - We have two scenarios: one with chloride ions (Cl⁻) and the other with bromide ions (Br⁻). 2. **Reaction with Chloride**: ...

How do you count for the following observations ? (a) Though alkaline potassium permanganate and acidic potassium permanganate both are used as oxidants, yet in the manufacture of benzoic acid from toluene we use alcoholic potassium permanganate as an oxidant. Why ? Write a balanced redox equation for the reaction. (b) When concentrated sulphuric acid is added to an inorganic mixture containing chloride, we get colourless pungent smelling gas HCl, but if the mixture contains bromide then we get red vapour of bromine. Why ?

What would you observe in the following ? Sugar crystals are added to a hard glass test tube containing concentrated sulphuric acid.

Give reason for the following within two sentences: i. Hydrogen bromide cannot be prepared by the action of concentrated sulphuric acid on sodium bromide. ii. When a blue litmus paper is dipped in a solution of hypochlorous acid, it first turns red then gets decolourised.

A mixture of two salt was treated as follows : i. The mixture was heated with magnanese dioxide and concentrated sulphuric acid , when a yellowish -green gas was liberated. ii. The mixture on heating with sodium hydroxide solution gave a gas which turned red litmus blue iii. Its solution in water gave a blue precipitate with potassium ferricyanide and red colourtion with ammonium thiocynate iv. The mixture was boiled with potassium hydroxide and the librated gas was bubbled through an alkline solution of K_(2)HgI_(4) to give a brown precipitate identify the two salts gives ionic equation for the reaction involved in the tests (i) , (ii) and (iii).

(i) You are provided with two test tubes containing an aqueous solution of carbonateand sulphite respectively. How will you identify them? (ii) A colourless salt on heating, forms a white sublimate on the cooler sides of the lost tube. The gas evolved is colourless and has a pungent smell. It givos donse white fumes when a rod dipped in conc. HCl is brought near the mouth of the fest tube. Identify the basic radical present in the salt.

When an aqueous solution of a colourless mixture of two salts is treated with a drop of chlorine water, the solution becomes brown. Some chloroform is added to the brown solution and the resulting mixture is shaken wel. The chloroform layer becomes violet. (ii) When chlorine water is again added dropwise to the above mixture, the chloroform layer becomes colourless. (iii) On being heated with solid K_(2)Cr_(2)O_(7) and concentrated H_(2)SO_(4) , the solid mixture gives vapours of a dark colour which form a yellow solution with aqueous NaOH. On acidification with acetic acid followed by treatment with lead acetate, the yellow solution gives a yellow precipitate. (iv) When boiled with an NaOH solution, the mixture gives a gas that produces thick white fumes with HCl vapours and turns nessler's reagent brown. the mixture does not respond to any other test for cations. (v) The mixture, on being heated, gets completely sublimed. Q. Which of the following reactions takes place in (ii) ?

(a) When concentrated sulphuric acid was added to an unknown salt present in a test tube a brown gas (A) was evolved . This gas intensified when copper turnings were added to this test tube . On cooling, the gas (A) changed into a colourless solid (B) . (i) Identify (A) and (B). (ii) Write the structures of (A) and (B). (iii) Why does gas (A) change to solid on cooling ? (b) Arrange the following in the decreasing order of their reducing character : HF , HCl , HBr , HI (c) Complete the following reaction : XeF_(4) + SbF_(5) to
