In class we did a lab in which we first dissolved copper II chloride powder in water to form a blue solution. We then placed a crumbled up piece of aluminum foil in that solution. It turned brown and the originally blue solution that came in contact with the aluminum turned colorless. The aluminum foil turned brown. My question here is, what is the brown substance on the aluminum foil, and how do you know it's not rust? Thanks in advance.
The aluminum foil is a thin sheet of solid aluminum. You can see that it is white colored or silver colored, if you prefer. So solid aluminum is white in color. Aluminum salts are colorless or you see them as white. When aluminum salts are dissolved in water, the solutions are colorless. Now, what is the color of solid copper? Remove the plastic insulation from a piece of electric wire to see the copper wire inside, or look at the copper bottom of a frying pan. You can see that copper is a brown solid. Copper II salts are blue in color. So when you dissolved Cu II chloride in water, you got a blue solution.
The blue color indicates the presence of Cu II ions in the solution. Aluminum is more reactive than copper. Therefore when aluminum foil is put into the copper salt solution, aluminum atoms on the surface of the foil in contact with the solution reacts and takes the place of copper II ions in the solution it now becomes aluminum chloride solution. That is why the blue solution becomes colorless. The copper II ions that were originally in the solution are pushed out to form solid copper powder brown and sticks on the surface of the aluminum foil in chemistry, we say that the aluminum "displaced" copper from the salt. So the brown coating which appears on the aluminum foil is solid copper.
Now how do you know that it is not rust? You must know that iron objects slowly rust as time passes. This is because the iron reacts with oxygen in the atmosphere and slowly changes to iron oxide in the presence of moisture. Chloride on the other hand can add an electron to become an anion, a negative charge ion. This creates a cube-shape and makes what we know as table salt. Red and black phosphorus are considerably more passive in chemical reactions. The oxidation of white phosphorus occurs through a chain reaction. The oxidation of phosphorus is often accompanied by chemiluminesce; an occurrence whereby light is emitted during a chemical reaction and not producing significant quantities of heat. Phosphorus combines directly with all halogens. When heated with metals, phosphorus forms phosphides.
Besides, he also states that the rate of random rearrangement is crucial since the trisaturated glycerides can precipitate as fast as they are produced in the liquid phase. Magnesium is an alkaline earth metal with an atomic number of 12 and an atomic mass of It is part of the second group of elements on the periodic table located on the far left side of the periodic table. At the same time hydrogen gains electrons to become a neutral molecule. I think that Magnesium is going to have the fastest reaction. Show More. High doses of magnesium in medicine and food supplements may cause muscle slackening, nerve problems, depressions and personality changes.
As was mentioned before, it is unusual to introduce legal limits for magnesium in drinking water, because there is no scientific evidence of magnesium toxicity. In other compounds, for example asbestos, magnesium may be harmful. Magnesium compounds are usually removed from water, because of the role magnesium plays in water hardness. This is achieved by means of water softening.
Magnesium hydroxide is applied as a flocculant in water purification. Literature and the other elements and their interaction with water. Toggle navigation. About Lenntech. General Delivery Conditions. Privacy Policy. All rights reserved. Magnesium is present in seawater in amounts of about ppm. After sodium, it is the most commonly found cation in oceans. Rivers contains approximately 4 ppm of magnesium, marine algae , ppm, and oysters ppm. Dutch drinking water contains between 1 and 5 mg of magnesium per liter. Magnesium and other alkali earth metals are responsible for water hardness.
Water containing large amounts of alkali earth ions is called hard water, and water containing low amounts of these ions is called soft water. In what way and in what form does magnesium react with water? Why is magnesium present in water? What are the environmental effects of magnesium in water? What are the health effects of magnesium in water? Which water purification technologies can be applied to remove magnesium from water?
