Magnesium sulfate is a medication used to manage and treat multiple clinical conditions and holds several on and offlabel uses. This activity outlines the indications, mechanism of action, and contraindications for magnesium sulfate as a valuable agent in treating magnesium electrolyte abnormalities, eclampsia, and constipation.
Magnesia, magnesium oxide, i s usually produced by calcining the mineral magnesite or magnesium hydroxide obtained from seawater or brine by liming. It is also produced by the thermal decomposition of magnesium chloride, magnesium sulfate, magnesium sulfite, nesquehonite, and the basic carbonate.10 A flow diagram of

PREPARATION OF 4g 20% SOLUTION OF MAGNESIUM SULFATE (MgSO4) ¨Wash hands thoroughly with soap and water or use alcohol hand rub and air dry. ¨Using a 20mL syringe, draw 12 mL of sterile water for injection.If 50% MgSO4. is available, add 8 mL of MgSO4 50% solution* to 12 mL of water for injection to make 20 mL of 20%
Hold the piece of magnesium metal ribbon in a pair of tongs. Take the lighter and hold the magnesium metal ribbon in the hottest part of the flame. It will soon catch fire and emit a very bright light. CAUTION DO NOT LOOK DIRECTLY AT THE BRIGHT LIGHT. Briefly gaze at the light out of the corner of your eye.
This is a useful class experiment to introduce energy changes in chemical reactions, suitable for 11–14 and 14–16 year olds. Students measure the temperature changes in different reactions taking place in a polystyrene cup, classifying the reactions as exothermic or endothermic. The experiments can also be used to revise different types of
