Redox reaction from dissolving zinc in copper sulfate
So what we have here is a solution of a copper sulfate. And copper sulfate is an ionic compound. The copper loses two electrons to the sulfate. So the copper has a positive 2 charge, and the sulfate has a negative 2 charge. This is a ion. This is an anion. So you could imagine it''s very easy to dissolve it in a polar solvent like water.
Determining the Empirical Formula | Protocol
Add a small quantity (~0.20 g) of aluminum metal to the beaker. This will cause the copper to reduce to a reddish metal, and the aluminum will oxidize to colorless Al 3+. The blue color of the solution should disappear as the Cu 2+ ions form Cu 0. After 30 min, add additional small pieces of aluminum to ensure all of the copper is reduced to

Oct 29, 2008· Aluminum ( AL) has a +3 charge. Nitrate is a coination of Nitrogen and Oxygen. NO_3 . That will have a -1 charge. Therefore to balance it we need 3 Nitrates to make aluminum nitrate. Al [ N O_3 ] _3. Here are some general chem notes on polyatomic ions. This should help you decide when to use - ide, ite, or ate, and the differences in terms of
Chemical Properties of Copper - Science Struck
Copper is a metal used by people who lived in prehistoric times. It is a good conductor of heat and electricity. Jordan, Egypt, and Israel have copper smelting loions that date back to 4500 B.C. The people who lived in that historical period coined copper with iron or tin to produce an alloy called bronze. Another alloy of copper is brass.
Chem4Kids: Aluminum: Orbital and Bonding Info
Because aluminum has three, that means three chlorine atoms can bond. They make the formula AlCl 3, also known as aluminum trichloride. Each of the chlorine atoms gets an electron to fill its shell, and the aluminum loses three, giving it a filled shell too (remeer, aluminum has three extra electrons).
Copper - Element information, properties and uses
Copper is not difficult to extract from it ores, but mineable deposits were relatively rare. Some, such as the copper mine at Falun, Sweden, date from the 1200s, were the source of great wealth. One way to extract the metal was to roast the sulfide ore then leach out the copper …

Uses of Copper - Uses Of
Since it was first used in 8000 B.C, people have discovered different uses of copper. Tools made of this element helped advance civilization during the Stone Age. Since that time, it has become an integral part of many industries. Architectural Appliions Copper is heavily employed in the construction industry. It is commonly found in buildings because it is waterproof. This makes it
What Are the Skin Benefits of Calcium? | Livestrong
Calcium is a common element in the human body. It is vital to the health of your bones, teeth and bodily organs, including the skin. Calcium plays a role in regulating the skin''s many functions. Most calcium in the skin is found in the epidermis, or the outermost layer of skin.
This will take care of many copper elimination symptoms. 3. Enhance the removal of copper from the blood stream by eating more cooked vegetables. This assists all elimination and replaces more minerals. 4. More coffee enemas are often wonderful for copper elimination symptoms. They stimulate bile flow and enhance liver detoxifiion.

What is the formula for aluminum nitrite? | Socratic
Apr 18, 2016· The formula for aluminum nitrite is "Al(NO"_2)_3". Aluminum nitrite consists of the aluminum ion "Al"^(3+)" and the polyatomic nitrite anion "NO"_2^(-)". Since an ionic compound must be neutral, the nuer of each ion must result in an overall charge of zero. Since the aluminum ion has a charge of 3+, and the nitrite ion has a charge of 1-, there need to be three nitrite ions for every
Removal of Copper (II) Ions from Contaminated Water by
Sodium chloride (NaCl) and sodium nitrate (NaNO 3) were used as salts. Calcium nitrate (Ca(No 3) 2) was used particularly because it disassociates into Ca +2, a positively charged ion with a +2 charge, which is the same as Cu +2. The first two salts barely affected the adsorption of copper, but calcium nitrate greatly decreased the adsorption

Reactivity Series of Metals - Get the Chart, Significance
2 Ca + O 2 → 2 CaO (calcium oxide) 4 Al + 3 O 2 → 2 Al 2 O 3 (aluminium oxide). The transition metals (such as iron, copper, zinc, and nickel) are slower to oxidize because they form a passive layer of oxide that protects the interior. Others, like palladium, platinum and gold do not react with the atmosphere at all.

Absorption of Minerals and Metals
Calcium. Calcium is absorbed from the intestinal luman by two distinct mechanims, and their relative magnitude of importance is determined by the amount of free calcium available for absorption: 1. Active, transcellular absorption occurs only in the duodenum when calcium intake is low. This process involves import of calcium into the enterocyte
