Preparation and Uses of Common Salts in Industry starts at 10 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Preparation and Uses of Common Salts in Industry. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

See sample questions for grade 10

Describe the process of obtaining magnesium sulfate from sea water.

Describe the process of preparing ammonium sulfate from ammonia and sulfuric acid.

Describe the process of preparing calcium sulfate from gypsum.

Describe the process of preparing sodium carbonate (washing soda) by the Solvay process.

Describe the role of sodium chloride in the preparation of sodium hydroxide.

Explain how potassium chloride is obtained from sylvite ore.

Explain the importance of calcium chloride as a by-product in the Solvay process.

Explain the importance of sodium chloride in the food processing industry.

Explain why ammonium nitrate is widely used in agriculture.

Explain why sodium carbonate is used in water softening.

Explain why sodium chloride is important in the chlor-alkali industry.

Name one use of ammonium chloride in industry.

State one major industrial use of sodium chloride.

Write the balanced chemical equation for the reaction between hydrochloric acid and sodium hydroxide to form sodium chloride.

A chemical plant needs to produce 500 kg of sodium carbonate (Na₂CO₃) using the Solvay process. If the overall yield of the process is 80%, calculate the minimum mass of sodium chloride (NaCl) required. (Molar mass: Na₂CO₃ = 106 g/mol, NaCl = 58.5 g/mol)

Describe the environmental concerns associated with the large-scale industrial production of salts such as sodium chloride and calcium chloride. Suggest one method to minimize these impacts.

Explain, with balanced chemical equations, how sodium sulfate is produced industrially from sodium chloride and sulfuric acid. Discuss the importance of this process in the manufacture of detergents.

State the chemical reaction and conditions required for the industrial preparation of potassium nitrate from potassium chloride and nitric acid. Why is this process important in agriculture?
