Metal ions in solution will be reduced, Metal ions are the oxidising agent. magnesium(s) + silver nitrate(aq) → magnesium nitrate(aq) + silver(s). The reducing agent in this reaction is the Mg as it will donate electrons to the silver ions . These are called ion-electron equations (or ionic half equations).
Silver is the metal that is present at the bottom of the reactivity series, below Mg and Cu metals. So, it cannot displace these metals from its solution. As a result, no reaction takes place with the piece of silver.
Reactions With
Oxygen: When exposed to oxygen, magnesium turns into magnesium oxide. Hydrogen: When exposed to hydrogen, magnesium turns into magnesium hydride. Nitrogen: When reacted with nitrogen, magnesium turns into magnesium nitride. Halogens: When reacted with a halogen, magnesium is very reactive.
Magnesium's susceptibility to corrosion occurs despite the presence of an oxide layer. This film, which also develops in other light metals such as aluminium, fails to adequately protect components in acidic and neutral environments, where it can corrode rapidly exposing the metal underneath to further attack.
As mentioned in the question, aqueous solution of magnesium chloride and silver nitrate when mixed results in the formation of solid silver chloride and aqueous magnesium nitrate. We can express this reaction in terms of molecular equations.
Metal ions in solution will be reduced, Metal ions are the oxidising agent. magnesium(s) + silver nitrate(aq) → magnesium nitrate(aq) + silver(s). The reducing agent in this reaction is the Mg as it will donate electrons to the silver ions . These are called ion-electron equations (or ionic half equations).
Aluminium will displace magnesium and a colorless solution will be obtained.
However, magnesium does corrode very quickly. Unlike the reddish brown rusted surface of iron corrosion, magnesium corrosion is actually more of dull gray film.
Magnesium is another element that is highly reactive, so it is not found in a pure state on Earth, unless a crazy-haired chemist has produced a pure chunk of vapor-deposited magnesium crystals using the Pidgeon process, as you see in the image at the top.
Magnesium and calcium/multivitamin
Additionally, she says to refrain from taking calcium, magnesium or zinc together as they will “compete for absorption.”
Antibiotics: Taking magnesium supplements may reduce the absorption of quinolone antibiotics, tetracycline antibiotics, and nitrofurantoin (Macrodandin). Magnesium should be taken 1 hour before or 2 hours after taking these medications. Quinolone and tetracycline antibiotics include: Ciprofloxacin (Cipro)
Magnesium does not react with water to any significant extent. This is in contrast with calcium, immediately below magnesium in the periodic table, which does react slowly with cold water.
Silver dissolves readily in nitric acid and in hot concentrated sulfuric acid. The metal will also dissolve in oxidizing acids and in solutions containing cyanide ions in the presence of oxygen or peroxides.
Silver is a very inactive metal. It does not react with oxygen in the air under normal circumstances. It does react slowly with sulfur compounds in the air, however.
When silver is exposed to sulfur-containing gases in the air, it discolours and then darkens as it reacts with the gas to form a surface layer of tarnish. This process is called tarnishing, as explained below in The science of silver tarnish and its cause.
Galvanic corrosion is the most influencing factor because magnesium corrodes when coupled with materials like steels, SS (stainless steels), Cu alloys (copper alloys), Al alloys (aluminium alloys), Ti alloys (titanium alloys).
Magnesium oxidizes when it comes into contact with oxygen, resulting in MgO forming during this process. This chemical reaction is known as oxidation-reduction or redox for short.
Magnesium is More Corrosion-Resistant
Magnesium is more resistant to corrosion than aluminum. This means it will rust less quickly when exposed to the elements, making it a good choice for outdoor applications.
Magnesium is more reactive than zinc and aluminum because it has lower ionization energy and a higher electron affinity. Magnesium is also less electronegative than zinc and aluminum, so it forms cations more easily.
2.2. Galvanic corrosion. Galvanic corrosion is a common corrosion feature of Mg alloys. For example, galvanic corrosion may occur when Mg parts are connected or welded with the steels in lightweight powertrains and automotive bodies.
Magnesium nitrate reacts with alkali metal hydroxide to form the corresponding nitrate: Mg(NO3)2 + 2 NaOH → Mg(OH)2 + 2 NaNO3.
A typical reaction with silver nitrate is to suspend a rod of copper in a solution of silver nitrate and leave it for a few hours. The silver nitrate reacts with copper to form hairlike crystals of silver metal and a blue solution of copper nitrate: 2 AgNO3 + Cu → Cu(NO3)2 + 2 Ag.
Aluminium nitrate may also be prepared a metathesis reaction between aluminium sulfate and a nitrate salt with a suitable cation such as barium, strontium, calcium, silver, or lead.
