How do you Calculate the total hardness of water sample that contains ppm magnesium and ppm calcium?

Answer will be (mg/L) as CaCO3

units of ppm are the same as mg/L.

Hardness = 2.5(mg Ca/L) + 4.1(mg Mg/L)

In this case: 2.5x78.4 + 4.1x104.5 = 624.45 mg/L

What is the number of ions in the element magnesium?

positive ion - magnesium(cation)

negative ion-chloride (anion)

Why does the magnesium atom tend to form the 2 ion?

Magnesium has two outer shell electrons which are loosely held. This is not a stable configuration. As a result magnesium will lose those two electrons, making the electron shell below that, which has 8 electrons, the new outer shell. An electron shel with 8 electrons is stable.

Where can you purchase Magnesium Citrate?

Hi,

I found your question online and I am looking for it as well. Did you find out where your can get the magnesium chloride powder?

Thank you

How bright is burning magnesium?

Magnesium will burn readily if it is in thin slices, powdered or slivered. In thicker, bar form, it resists burning much better. However, if you happen to get a thick piece of magnesium burning, it is impossible to extinguish without a "type-D" fire extinguisher (used specifically for magnesium fires and nothing else). A thick piece of magnesium will burn for a long, long time.

Is magnesium chromate covalent or ionic?

It is ionic. The dichromate ion, Cr2O72-, with the structure [O3Cr-O-CrO3]2-, consists of covalently bonded oxygen and chromium atoms (the electronegativities of Cr and O are 1.6 and 3.5, respectively, so the bonds are highly polar). This oxyanion is bonded ionically to magnesium ions, Mg2+. See Cotton and Wilkinson, Advanced Inorganic Chemistry, for more on the dichromate ion. Magnesium dichromate is the only alkaline earth dichromate that is appreciably soluble in water.

How long is the shelf life for mild of magnesia?

The shelf life of milk of magnesia is typically about 2 to 3 years when stored properly in a cool, dry place and kept tightly sealed. It's important to check the expiration date on the packaging, as effectiveness can diminish over time. Always discard any product that appears cloudy, changes color, or has an unusual odor. If in doubt, consult a pharmacist or healthcare provider.

Is magnesium a pure substance?

Yes. Magnesium oxide is a compound which is a type of pure substance.

Why might a plant deficient in magnesium grow pale leaves?

A plant deficient in magnesium may grow pale leaves because magnesium is essential for chlorophyll production, the pigment responsible for the green color in leaves and the process of photosynthesis. Without adequate magnesium, chlorophyll production is impaired, leading to yellowing or pale leaves, a condition known as chlorosis. This deficiency also affects the plant's ability to synthesize carbohydrates, ultimately hindering growth and overall health.

What percentage of sodium hypochlorite is in milk of magnesia?

Sodium hypochlorite is not in milk of magnesia.

Milk of magnesia is magnesium hydroxide and water.

Is magnesium bromide giant or simple structures?

A giant structure. MgBr2 is ionic and forms an ionic lattice.

Does magnesium come in a liquid form?

Magnesium is primarily found in solid form, such as in metal or powder. However, magnesium salts, like magnesium chloride or magnesium sulfate, can be dissolved in water to create liquid solutions that contain magnesium. These solutions are often used in supplements and medical applications. So, while elemental magnesium itself is not liquid, magnesium compounds can exist in liquid form when dissolved.

How many grams are in 5.2 moles of magnesium sulfide?

Mass in grams = no of moles x molecular mass.

So, mass in grams = 5.2x 56 = 291.2g
