Does magnesium hydroxide dissolve in water?

Magnesium oxide does not "dissolve" in hydrochloric acid. Dissolution is a physical change. When magnesium oxide is mixed with hydrochloric acid, a chemical reaction takes place:

Mg(s) + 2HCl ---> MgCl2(aq) + H2(g)

Is magnesium sulphate deliquescent?

No. Mg(NO3)2 has to be heated to dissociate to MgO, NO2 and O2.

How does milk of magnesia react to stomach acids?

Milk of magnesia does not act as a good buffer because the level of ph doesn't change rapidly. The ph needs to change for anything, acid or base.

What is the percentage of magnesium?

The abundance of magnesium for a sample of 19 main sequence B-type and 41 magnetic chemically peculiar stars has been derived by spectrum synthesis analysis of the MgII448.1nm line under the LTE assumption.

Why is magnesium is expensive than aluminum?

The long answer would factor in the commercial market for metals as commodities and the relative abundance of magnesium ore and iron ore in certain geographic areas. The short answer, and the one more relevant to chemistry, is that magnesium is higher on the reactivity series than iron, and thus is slightly harder to separate from its compounds.

What is magnesium glycerophosphate?

Magnesium glycerophosphate is a compound formed from magnesium and glycerophosphoric acid. It is commonly used as a magnesium supplement due to its high bioavailability and ability to support various functions in the body, such as muscle and nerve function. It may also help in maintaining healthy bones and heart rhythm.

Why does magnesium displace copper from copper sulphate?

This is a simple displacement reaction - the more reactive magnesium displaces the less reactive copper from a solution of its salt. ....

magnesium + copper sulphate ---> copper + magnesium sulphate

Mg + CuSO4 ----> MgSO4 + Cu

the blue colour of the copper sulphate will disappear and the silver coloured magnesium will be replaced by brown-red copper metal.

Why is magnesium maleable?

Magnesium is malleable because of its hexagonal close-packed crystal structure, which allows its atoms to easily slide past each other when external force is applied. This crystal structure gives magnesium its ability to be hammered or rolled into thin sheets without breaking.

Where why and how was magnesium discovered?

Magnesium was first isolated by Sir Humphry Davy in 1808 through the electrolysis of magnesium oxide. It was discovered in England. Magnesium takes its name from Magnesia, a region in ancient Greece where a mineral called magnetite (magnesium carbonate) was discovered.

Why milk magnesia is basicity in the pH scale?

the pH of milk of magnesia is important because it lowers the pH of the acid in your stomach

Does magnesium have magnetism?

No, it is not. Magnesium has no unpaired electrons. To be magnetic, a metal must have at least one unpaired electron (i.e., a spin up electron without a corresponding spin down electron). In general, response to a magnetic field is a property of electron spin.

What is maximum daily dosage of magnesium?

Magnesium can be taken at any age. This depends on why you are taking it. Many people are magnesium deficient.

What is the empirical formula for magnesium oxide?

MgCl2 is the correct formula, or two atoms of Cl for each 1 atom of Mg. You could also say 2 moles of Cl atoms for every 1 mole of Mg atoms. The empirical formula should be written with the subscripts in lowest whole number terms.

Note that this formula is consistent with the fact that an Mg cation is Mg+2 and a Cl anion is Cl-1. Given these charges, a formula of MgCl2 is the one with the smallest whole number subscripts that will allow the charge of the compound to be zero.

See related question below for more details on how to find empirical formulas.

How can you tell an ionic bond is formed between magnesium and oxygen?

it is ionic bonding because magnesium is a metal and oxygen is not. ionic bonding occurs between a metal and non-metal

Will silver react with a soulution of magnesium sulphate?

Chemical Equation for Reaction:

Reaction:

MgCl2 + 2AgNO3à 2PbCl + Mg (NO3) 2

White Precipitate Formed

Is magnesium a ferromagnetic?

No.

Added: They are not necessarily magnetic in and of themselves, but magnets ARE attracted to them (e.g.: Iron is a ferrous metal. A magnet is attracted to iron).

Can Magnesium give you diarrhea?

Magnesium salt it can cause severe diarrhea.

How does calcium's first ionization energy compare to the first ionization energy of magnesium and potassium?

First ionization energy of magnesium = 870/ kj/mol

First ionization energy of phosphorous = 589 kj/mol

So, magnesium has the larger ionization energy required to pull the first valance electron. Do you know why?

If lead oxide is heated with magnesium?

when it reacts with leadoxide it become magnesuim oxide. this is because they lead and magnesuim have undergone a REDOx (reduction and Oxidation).

the lead has been reduced and they magnesium has be oxidised!!!!!
