Tag: sulfur and its oxides

Normal rain water is slightly acidic (pH is 5-6)

Acid rain contains acids formed due to combination of sulphur and nitrous oxides present in the smoke discharged by the industries. These acids are highly corrosive in nature and cause rusting of metal assemblies. Also can affect structures like Taj Mahal by reacting with their material of construction. Moreover, can affect the fertility of soil. So, All of the above is the answer.

Bleaching action of $SO _{2}$ is due to its reduction property. It takes up oxygen from coloured material and makes it colourless.

Lead-acid batteries are made up of plates of lead and separate plates of lead dioxide, which are submerged into an electrolyte solution of about $38%$% $H _2SO _4$ and $62$% water.

Fossil fuels are made of sulphur so on burning they form sulphur dioxide as a product.

The chemical formula of king of chemicals, sulphuric acid is $H _2SO _4$. It is a dibasic acid and forms two types of salts
 $\displaystyle NaHSO _4$ (sodium hydrogen sulphate) and $\displaystyle Na _2SO _4$ (sodium sulphate).

$\text{sulphur dioxide can dissolve the limestone.}$

Sulphuric acid is oxidising agent and can not be used in white paint as it may react with some materials and produce sulphides which are usually coloured.

$H _2SO _4$ acid can act as oxidising agent when it is concentrated and can also sulphonate aromatic compounds.

Sulfur dioxide is the product of the burning of sulfur or of burning materials that contain sulfur.  It is produced by petrol combustion, coal combustion, petrolrefining and smelting operation.
