How to prepare magnesium sulphate salt in a labarotory ?

To prepare magnesium sulfate salt in a laboratory, you will need the following materials:

- Magnesium oxide (MgO)
- Sulfuric acid (H2SO4)
- Distilled water
- Beakers
- Stirring rod
- Filter paper
- Funnel
- Bunsen burner
- Tripod stand
- Wire gauze
- Evaporating dish

Here is the step-by-step procedure to prepare magnesium sulfate salt:

1. Measure out the required amount of magnesium oxide (MgO) and place it in a beaker.
2. Slowly add sulfuric acid (H2SO4) to the magnesium oxide while stirring continuously. Be cautious as the reaction is exothermic and can release heat.
3. Continue adding sulfuric acid until all the magnesium oxide has dissolved and no more gas is being produced.
4. Filter the solution using filter paper and a funnel to remove any impurities.
5. Transfer the filtered solution to an evaporating dish.
6. Heat the solution gently using a Bunsen burner on a tripod stand with a wire gauze to prevent direct contact with the flame.
7. Continue heating the solution until all the water has evaporated, leaving behind magnesium sulfate salt crystals.
8. Allow the crystals to cool and then collect them using a spatula.
9. Store the magnesium sulfate salt in a dry, airtight container for future use.

Note: Always wear appropriate personal protective equipment, such as gloves and goggles, when working with chemicals in a laboratory. Follow all safety precautions and guidelines to prevent accidents and injuries.
