Magnesium is placed in cold and hot water. The magnesium will not react well with the cold water, but it will react in hot water that produces magnesium hydroxide. Using a universal indicator or phenolphthalein, the hydroxides’ formation can be shown. To the class, use the demo camera to film the demonstration. The class will discuss the effects of temperature on magnesium’s reactivity in water and kinetics. At 10:30 p.m., the experiment is shown at the end of the class at University of Cambridge University in Cambridge, England.
How Does Magnesium React In Water – Answer & Related Questions
Magnesium reacts with hot water to produce magnesium hydroxide and hydrogen gas much faster. Magnesium hydroxide is insoluble in water and is barely basic, and it responds to the universal indicator, turning the solution blue/green or with phenolphthalein to turn the solution pink.
