NOTE

SULPHUR 2

Compounds of sulphur

Sulfur forms various compounds, including hydrogen sulfide (H2S), sulfur dioxide (SO2), sulfuric acid (H2SO4), and sulfides. These compounds have diverse applications in industry and occur naturally in processes like volcanic activity and the sulfur cycle.

Industrial preparation of Sulphuric acid (H2SO4)

Sulfuric acid (H2SO4) is a highly corrosive and strong mineral acid. It is often referred to as the "king of chemicals" because of its extensive use in various industrial processes. Some key properties and applications of sulfuric acid include:

Sulfuric acid is industrially prepared through the Contact Process. Here are the key steps:

 

  1. Sulfur Combustion:

 NOTE:  This method allows for the continuous production of sulfuric acid on an industrial scale.

Uses of Sulphuric acid

Sulfuric acid (H2SO4) has numerous industrial applications, including:

  1. Fertilizer Production:

   - Used in the production of phosphate fertilizers, such as superphosphate.

  1. Chemical Manufacturing:

   - Key in the production of various chemicals, including hydrochloric acid, nitric acid, and synthetic detergents.

  1. Petroleum Refining:

   - Employed in alkylation processes to produce high-octane gasoline.

  1. Metal Processing:

   - Used in pickling (cleaning) metal surfaces before plating or coating.

  1. Battery Manufacturing:

   - Essential in the production of lead-acid batteries, commonly used in vehicles.

  1. Water Treatment:

   - Used for pH control in water treatment plants.

EVALUATION:   1. Identify two compounds of sulphur.

  1. Discuss the industrial preparation of sulphur
  2. Mention 4 uses of Sulphuric acid.

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
