0.1 N Sulphuric Acid Solution: Properties and Uses
What is 0.1 N Sulphuric Acid Solution?
A 0.1 N sulphuric acid solution is a solution of sulphuric acid (H2SO4) that has a normality of 0.1. Normality is a measure of the concentration of a solution, and it is defined as the number of gram equivalents of a solute per liter of solution. In the case of sulphuric acid, one gram equivalent is equal to one mole of H2SO4 divided by two, since sulphuric acid is a dibasic acid.
To prepare a 0.1 N sulphuric acid solution, 5.75 mL of concentrated sulphuric acid (98% H2SO4) is mixed with water to make 1 liter of solution.
Physical Properties
A 0.1 N sulphuric acid solution has the following physical properties:
- Appearance: Clear, colorless liquid
- Odor: Pungent, irritating
- Density: 1.07 g/mL
- pH: Approximately 1.2
- Boiling Point: 100°C
- Freezing Point: -10°C
Chemical Properties
A 0.1 N sulphuric acid solution has the following chemical properties:
- Strong Acid: Sulphuric acid is a strong acid, which means it completely dissociates in water to produce H+ ions.
- Oxidizing Agent: Sulphuric acid is a strong oxidizing agent, which means it can oxidize other substances to produce water and a salt.
- Corrosive: Sulphuric acid is highly corrosive and can react with metals and other materials to produce hydrogen gas and a salt.
Uses
A 0.1 N sulphuric acid solution has several uses, including:
Laboratory Applications
- As a strong acid in chemical reactions and synthesis
- As an oxidizing agent in chemical reactions
- As a catalyst in certain chemical reactions
Industrial Applications
- In the production of fertilizers, detergents, and other chemicals
- In the treatment of wastewater and industrial effluents
- In the manufacture of explosives, dyes, and other chemicals
Medical Applications
- As an ingredient in some medications, such as ophthalmic solutions
- As a disinfectant and antiseptic in medical settings
Precautions and Safety Measures
When handling a 0.1 N sulphuric acid solution, it is important to take certain precautions and safety measures, including:
- Wearing protective equipment, such as gloves, goggles, and a face mask
- Handling the solution in a well-ventilated area
- Avoiding contact with skin and eyes
- Neutralizing spills with a base, such as sodium carbonate
- Storing the solution in a secure, well-ventilated area
By following these precautions and safety measures, you can minimize the risks associated with handling a 0.1 N sulphuric acid solution.
