Tin contains only 5 - 10 % of tin as SnO...

Tin contains only 5 - 10 % of tin as `SnO_(2)`, the rest being Siliceous matter, wolfram and pyrites of iron copper and arsenic. It is not attached by water. Only molten tin reacts with steam liberating hydrogen. In stannous oxide, tin is +2 oxidising state. So stannous oxide is also described as tin (II) oxide
Which of the following ionic species is more stable

A

`Sn^(+2)`

B

`Sn^(+4)`

C

`Ge^(+2)`

D

`Pb^(+4)`

Text Solution

Verified by Experts

The correct Answer is:
A
Down the group lowest oxidation state is more stable. Due to inert pair effect,
`Sn^(+2)gtSn^(+4)`

The process ofcorrosion ofiron is known as rusting. Rust appears to be a hydrated ferricoxide Fe_2O_3, xH_2O, Both O_2 & H_2O are required for rusting. Iron can be protected from the rusting by use of following compounds. i) Applying paints, lacquers and enamells on the surface ofiron ii) By forming a firm and coherent protective coating of ferroroferric oxide. This is done by passing steam over hot iron iii) By coating a thin film of Zinc, Tin, Nickel, chromium, aluminium etc, on the surface of iron If plated with Zinc, the reaction of products of Zinc with O_2 and H_2O form a coating which sticks to the surface and there by protects iron Zinc protects iron from corrosion because

    Passage-I : Metallic sulphates can be obtained by reacting the metals (above hydrogen in ECS), or its oxide, hydroxide or carbonate with dil. H_(2)SO_(4) . Group IA metals also form hydrogen sulphates which can be isolated in solid. In general metal sulphates are soluble in water and crystallize with water of crystallization. Sulphates are thermally more stable than nitrates. Select the stable hydrogen sulphate which can be obtained in solid state:

    Iodine titration can be iodemotire or iodimetric depending on using iodine directly or indirectly as an oxidising agent in the redox titration. a) Iodimetric titration in which a standard iodine solution is used as an oxidant and iodine is directly or indirectly titrated against a reducing agent. For example 2CuSO_(4)+4KIrarrCu_(2)I_(2)+2K_(2)SO_(4)+I_(2) b) Iodimetric procedures are used for the determination of strength of reducing agent such as thiosulphates, sulphites, arsenties and stannous chloride etc., by titrating them against standard solution of iodine in a burette. 2Na_(2)S_(2)O_(3)rarr2NaI+Na_(2)S_(4)O_(6) Starch is used as indicator near the end point which form blue colour complex with I_(3)^(-) . The blue colour disappeams when there is no more of free I_(2) . When 319.0 gm of CuSO_(4) in a solution is related with excess of 0.5 M KI solution, then librated iodine required 200 ml of 1.0 M Na_(2)S_(2)O_(3) for complete relation. The percentage purity of CuSO_(4) in the sample is
