Applications and Experiments for Magnesium Oxide Light
Magnesium oxide is the standard example of a basic metal oxide: shaken with water it gives a weakly alkaline suspension that turns red litmus blue. It also suits methods that name MgO, and with it students can practise weighing and dispensing fine powders under supervision.
- Class 10 science: showing that metal oxides such as magnesium oxide are basic, using Red Litmus Paper, which bases turn blue.
- Class 11 chemistry: properties of alkaline earth metal compounds.
- B.Sc. inorganic chemistry: reactions of magnesium oxide with acids to form magnesium salts.
- Analytical methods that specify MgO, with portions moved by a 115 mm porcelain Spoon-Spatula and dried samples kept in a Glass Desiccator.
Avoid breathing the fine dust, swallowing it or getting it in the eyes, and keep the container closed and dry. It is not for food, cosmetic, pharmaceutical or agricultural use. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Standard Scope of Supply
Magnesium Oxide Light is supplied in a closed container with a label giving batch, grade and hazard information, together with its Safety Data Sheet. The net weight per container is set out on the quotation, and spatulas, balances or litmus paper can be added to the same quotation if needed.
Packing, MOQ and Lead Time
We can quote one container or a bulk quantity for several laboratories. The quotation lists the pack size, packing, delivery time and price, and other oxides, salts and indicators needed for the same practicals can be added to it in one go.
Science Lab Supplies is a registered exporter holding an Importer-Exporter Code, so it can ship to buyers in Tanzania, Uganda, the UAE, Saudi Arabia, Oman and the Philippines. To request a price for magnesia, describe the quantity on the contact page, queue it with other reagents in the enquiry cart, or check tender terms on the lab tender page.
Frequently Asked Questions
What does “light” mean in Magnesium Oxide Light?
Light usually indicates a form of magnesium oxide with lower bulk density than heavy magnesium oxide. The bulk density of the batch you are offered is confirmed on the quotation; ask through the contact page if your method depends on it.
What are the formula and CAS number?
Magnesium oxide has the formula MgO, CAS number 1309-48-4 and a molecular weight of about 40.3 g/mol. It is also called magnesia or magnesium monoxide.
Can Magnesium Oxide Light be used in schools?
Yes, in authorised school laboratories under trained supervision. Students should avoid raising and breathing the dust and should wear eye protection when handling the powder.
Who supplies Magnesium Oxide Light?
This reagent is quoted by Science Lab Supplies from Ambala, India; schools, colleges, research laboratories, contractors and distributors receive the price, pack size and batch details directly, for one container or many.
