How can we get magnesium hydroxide from magnesium ribbon write with chemical reaction?

When the magnesium oxide formed by burning of magnesium ribbon in air is dissolved in water, it gives magnesium hydroxide.

How is magnesium oxide prepared?

Magnesium oxide is produced by heating magnesium carbonate at atmospheric pressure, preferably as the mineral magnesite, to its dissociation temperature of about 800°C–1000°C.

What can you do with magnesium ribbon?

It burns in air with a brilliant white light, and for this reason is often used in flares and fireworks. Magnesium is used in disposable flash bulbs to generate light for photography, but this use has been largely supplanted by other sources of illumination.

Why should we clean the magnesium ribbon with sand paper?

Like rusting in case of iron, with magnesium, the oxide layer forms a white coating on the outside of the metal that will slow down or interfere with the burning process. Rubbing with sand paper helps to remove this oxide layer due to which burning speeds up.

How do we get magnesium hydroxide solution?

Magnesium hydroxide, Mg(OH)2, is a white powder produced in large quantities from seawater by the addition of milk of lime (calcium hydroxide). It is the primary raw material in the production of magnesium metal and has been used as a fire-retardant additive.

How is magnesium hydroxide prepared from magnesium?

Preparation. Combining a solution of many magnesium salts with alkaline water induces precipitation of solid Mg(OH)2: Mg2+ + 2OH− → Mg(OH)

How hot does magnesium ribbon burned?

Magnesium is also flammable, burning at a temperature of approximately 2500 K (2200 °C, 4000 °F). The autoignition temperature of magnesium is approximately 744 K (473 °C, 883 °F). The extremely high temperature at which magnesium burns makes it a handy tool for starting emergency fires during outdoor recreation.
