Sulphuric Acid
​

Answer 1

Here is your answer:
H2SO4

Answer 2

$\large\bold{Sulphuric \: acid}$

Sulphuric acid is also know as oil of vitrols.

▶Formula of sulphuric acid is :--

$\large \boxed{\bold{H_2SO_4}}$

▶It is a strong and a non volatile acid and is also known as "king of acids" as is of high use.

▶Sulphuric acid is dibasic as it ionises in aqueous solution to give out two hydrogen ion.

▶It shows all acidic properties like:-

◼When reacted with a metal gives out a colourless odorless gas hydrogen.

$2Na + H_2SO_4 \longrightarrow Na_2SO_4+ H_2\uparrow$

◼When react with a carbonates or bicarbonate to give salt water and carbon dioxide.

$Na_2CO_3 + H_2SO_4 \longrightarrow Na_2SO_4+ H_2O + CO_2$

◼When reacys with a sulphite or sulphide to give sulphur dioxide.

$Na_2SO_3 + H_2SO_4 \longrightarrow Na_2SO_4+ H_2O + SO_2$

◼Reacts with a base or metallic oxide to give out salt and water.

$2NAOH + 2H_2SO_4 \longrightarrow Na_2SO_4+ 2H_2O$

▶Concentrated sulphuric acid is an strong oxidising agent which involves addition of oxygen and removal of oxygen as it gives out nascent oxygen on thermal decomposition.
