Often asked: Sulphuric Acid Questions And Answers?

Why do we add Sulphuric acid to water?

When acid is poured into water, it flows down the flask and mixes much better, so no boiling occurs. The reason this occurs is due to the large amount of energy released in the hydration reaction of sulfuric acid ions.

What are the three uses of Sulphuric acid?

The major use of sulfuric acid is in the production of fertilizers, e.g., superphosphate of lime and ammonium sulfate. It is widely used in the manufacture of chemicals, e.g., in making hydrochloric acid, nitric acid, sulfate salts, synthetic detergents, dyes and pigments, explosives, and drugs.

Which property of Sulphuric acid is used in the following?

Which property of sulphuric acid is used in the following:i As a source of hydrogen when treated in dilute form with metals like Zn Mg Fe etc. ii Production of hydrogen chloride on treating concentrated add with sodium chloride. iii Production of sulphur dioxide on heating in concentrated form with copper turnings.

What is the major use of Sulphuric acid?

Uses of sulfuric acid By far the largest amount of sulfuric acid is used to make phosphoric acid, used, in turn, to make the phosphate fertilizers, calcium dihydrogenphosphate and the ammonium phosphates. It is also used to make ammonium sulfate, which is a particularly important fertilizer in sulfur-deficient.

Can you mix sulfuric acid with water?

When you mix concentrated sulfuric acid and water, you pour the acid into a larger volume of water. Sulfuric acid (H2SO4) reacts very vigorously with water in a highly exothermic reaction. If you add water to concentrated sulfuric acid, it can boil and spit and you may get a nasty acid burn.

Can you put sulfuric acid in the toilet?

Acidic drain cleaners made of sulfuric or hydrochloric acid are powerful enough to clear heavy-duty hair, food, grease, soap scum, or paper-based clogs in 15 minutes or less. Acidic drain cleaners are generally safe for newer plastic or metal pipes (e.g., copper) in sink, tub, shower, and toilet drains.

What is the pH of sulfuric acid?

pH of Common Acids and Bases

Acid Name 1 mM
H2SO4 sulfuric acid 2.75
HI hydroiodic acid 3.01
HBr hydrobromic acid 3.01
HCl hydrochloric acid 3.01

Who uses sulfuric acid?

Uses of Sulphuric Acid Sulphuric acid is highly acidic. Therefore, it is used in the cleaning of metals, removal of impurities from oil, manufacturing of chemicals – nitric acid, hydrochloric acid, synthesis of dye, drugs, detergents, explosives, etc.

How fast does sulfuric acid gas kill?

The deadly numbers and statistics from H2S gas 800 ppm is the lethal concentration for five minutes of exposure. Concentrations over 1000 ppm cause immediate collapse with loss of breathing, even after inhalation of a single breath – death can occur within one to four hours of exposure.

What is the nature of Sulphuric acid?

Sulfuric acid is also known as Mattling acid or Oil of vitriol. It has a strong acidic nature and is corrosive. At higher concentrations, it acts as an oxidizing agent and dehydrating agent. It is a syrupy liquid which is odourless and has no colour.

Why Sulphuric acid is non volatile?

Sulphuric acid has a high boiling point. Due to it’s non – volatile nature, it is used to prepare volatile acids such as HCl, HNO3 and acetic acid from their salts.

What is the name given to the salts of Sulphuric acid and sulfuric acid?

The name given to the salts of sulphurous acid is Hydrogen sulphites and Sulphites.

Is sulfuric acid man made?

Sulfuric acid is prepared industrially by the reaction of water with sulfur trioxide (see sulfur oxide), which in turn is made by chemical combination of sulfur dioxide and oxygen either by the contact process or the chamber process. 4 дня назад

What are the hazards of sulfuric acid?

If sulfuric acid makes direct contact with the eyes, it can cause permanent blindness. If ingested, this chemical may cause internal burns, irreversible organ damage, and possibly death. Exposure to sulfuric acid aerosols at high concentrations leads to severe eye and respiratory tract irritation and tissue damage.

What is the chemical formula of sulfuric acid?
