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.

The most important man-made sources of sulfur dioxide are fossil fuel combustion, smelting, manufacture of sulfuric acid, conversion of wood pulp to paper, incineration of refuse and production of elemental sulfur.

The air pollution by $SO _2$ can cause Corneal haze, breathing difficulty, airways inflammation, eye irritation, psychic alterations, pulmonary oedema, heart failure and circulatory collapse in human beings.  

Fuel additives such as calcium additives and magnesium carboxylate may be used in marine engines to lower the emission of sulfur dioxide gases into the atmosphere.
