Calcium

Potassium iodide is neutral. So any solution of potassium iodide would have a pH of 7.

One note: no substance has a particular pH as pH depends on both the acidity/basicity of a substance and how concentrated it is.

Yes, you can take too much calcium, according to Dr. Toohey, who says that 2500 mg. is the maximum amount one should consume, whether by diet or supplements. You can read about Dr. Toohey's opinion here: http://www.chronicfatigue.org/What's%20New.html Evidently when you take in too much calcium, it can cause other health problems such as kidney stones. It is best to get your calcium from food sources, as they are absorbed into the body better. Ruth Hendrickson

Yes, butter has calcium, even though you should not use it as a primary source for your calcium.

Too much calcium will result in a high pH. This will cause the nutrients to become too concentrated and they will eventually kill the plant.

Yes,Sorel in 1867 announced the discovery of an excellent cement formed from the combination of magnesium oxide and magnesium chloride solution. This cement type is known by many different names, such as Sorel, magnesite and magnesium oxychloride cement. This cement has many superior properties to Portland cement. However, there are two other known magnesia cements. The first is magnesium oxysulfate (MOS), which is the sulfate analogue of magnesium oxychloride and is formed by the combination of magnesium oxide and magnesium sulfate solution. The second is magnesium phosphate cement (MAP), formed by the reaction between magnesium oxide and a soluble phosphate, such as ammonium phosphate monobasic (NH4H2PO4)

We can find calcium as a non metal element. Atomic number of it is 20.

The radius of a cadmium atom is smaller than the radium of a mercury atom. The trend for atomic radius is that the radius becomes larger toward the left side of the row and toward the bottom of the group.

Calcium carbide lamps have been used (historically in mines) to create light by immersing calcium carbide in water to produce acytelene gas, which burns and creates light. Although they work as lamps, the gas produced by them makes them less safe than oil lamps, and as such they were usually only used in industrial lighting rather than in homes. Electrical lighting is usually safer than either oil or carbide lamps because there is less danger of fire.

yes-potassium will blow up on contact with air or water and other materials or elements. potassium forms many compounds such as potassium chloride, which is a lethal poison used to kill people on death row in the united states. potassium is important in your diet, as it helps carry nerve impulses to and from your brain. potassium is commonly found in bananas. potassium is more reactive than even sodium.

Calcium Carbonate is insoluble chemical compound so all you have to do is decant or filter.... think about this, how do you separate sea shells from water? sea shells are made from calcium carbonate, that's why you see then on the beach all the time because they are insoluble.

Calcium hydroxide has molecular formula Ca(OH)2, so its elements are Calcium, Oxygen and Hydrogen.

high protein can lead to kidney stones.

high calcium can lead to deposits in bone joints. youll hear or feel your bones more.

Answer is Vitamin D.(1,25 bihydroxycholecalciferol. )

This used to be a very tough problem. Fortunately now made easier with a new chemical breakthrough. Spray Power Blue Scale Off directly onto the scaled over tile. Brush with a non-metallic pad type brush (like a scotch brite scrubby pad) what is begin to fizz, brush and spray till scale is all gone, then rinse.

You can google the name and buy it online.

There are several ways. Best that I now of is glass-beads-blasting. You need to have a good Pool Service person do this. THEN you should balance the water (especially TA) to prevent the same thing happening again. We can supply more info through discussion.

Calcium carbonate (CaCO3) consists of one calcium ion (Ca2+) and one carbonate ion (CO3^2-). Therefore, the percentage of calcium ions in calcium carbonate is calculated as: (Atomic mass of calcium / Molecular mass of calcium carbonate) x 100 = (40.08 / 100.09) x 100 = 40.02% Therefore, calcium ions make up approximately 40.02% of the total mass of calcium carbonate.

Ca2+

No, it is not. All oxides are insoluble except for group I oxides

yes it is found in lime yes it is found in lime.

I know there are many other diseases and things that will take the calcium from the bones. But the only one I am very familiar with is hyperparathyroidism. Its basically a problem with the parathyroid gland. It takes calcium out of the bones and puts more into the blood. Thus causing weak bones. Im going to the doctor to get tested for this soon.

Phosphorus is an essential mineral that is required by the body to function normally. It is mainly found in the body in the form of phosphates. Phosphorus is a critical component of all living organisms since it performs very important functions

you need to do what is called a back-titration, by reacting the seashell (ground up very fine) with an acid, then titrating the solution with a base. the data can then be used to find the moles of CaCo3, and from there you can go to grams. Divide grams CaCo3 by the mass of seashell used, then multiply by 100 to find the percentage

See http://www.fiu.edu/~pricer/Calcium%20Carbonate.pdf.

The solubility of CaCO3 depends on the solubility of CO2. The solubility of gases decreases in water as the temperature rises. This behavior is discussed at http://antoine.frostburg.edu/chem/senese/101/solutions/faq/temperature-gas-solubility.shtml.
