If 5.25 g of MgCl2 is dissolved in 200.0 ml of solution calculate the concentration( molarity) of MgCl2, the magnesium ion, and the chlorine ion?
Atomic weight for Mg is 24.305, for Cl is 35.453.
Molecular weight for MgCl2 is 24.305 + 2(35.453) = 95.211.
Molarity for the MgCl2 solution made with 5.25 g of the salt
diluted to 200 ml is,
M = [5.25/95.211] x [1/0.200 liter] = 0.2757 Molar
Assuming 100 % ionic dissociation,
Molarity of Mg+2 is 0.2757
and for Cl- is twice, 0.5514

What is the name of a compound made from magnesium and chlorine?
When compounding magnesium and chlorine you get the compound, magnesium chloride, MgCl2, dissolved in seawater, is an abundant, natural source of the very useful metal magnesium. Magnesium is a common component of alloys. Alloys are produced by combining a pure metal with one or more other elements to form a new substance with desirable properties.
How do you calculate dose using granular chlorine?
To calculate the dose of granular chlorine needed, you first need to know the volume of water to be treated and the desired chlorine concentration. Then, you can use the formula: dose (in pounds or grams) = volume of water (in gallons or liters) x desired chlorine concentration (in ppm) / 10,000. This will give you the amount of granular chlorine needed to achieve the desired concentration in the water.
What is the pH of chlorine?
Chlorine itself does not have a pH since it is a pure element. However, when dissolved in water, chlorine forms hydrochloric acid which can lower the pH of the solution depending on the concentration.
What is chlorine plus magnesium bromine?
Chlorine + Magnesium Bromide ----> Magnesium Chloride + Bromine
Where did the chlorine in the magnesium chloride come from in the reaction?
The chlorine in magnesium chloride comes from the chlorine gas that is used in the reaction. When magnesium reacts with chlorine gas, the two elements combine to form magnesium chloride.
Where did chlorine in the magnesium chloride come from in this reaction?
Chlorine in magnesium chloride typically comes from chlorine gas (Cl2) being reacted with magnesium metal (Mg) in a chemical reaction. The chlorine ions are transferred to magnesium to form magnesium chloride (MgCl2), resulting in the incorporation of chlorine into the compound.
Does magnesium react with chlorine?
Yes. At standard temperature and pressure, magnesium in contact with chlorine will react to form magnesium chloride.
What is the combined percentage of magnesium and sulfur in the dissolved solids in ocean water?
there is a circular graph that shows sodium in 30.6% chlorine is 55.0%, magnesium is 7.7% and sulfur is 3.7%percentge the close ones are calcium which is 1.2%, potassium which is 1.1% and others is 0.7 %
What are the properies of magnesium chloride?
magnesium and chlorine
What formula do you get when you combine the elements chlorine and magnesium?
The chemical formula of magnesium chloride is MgCl2.
What is the difference between MgCl and MgCl2?
MgCl is magnesium chloride with a 1:1 ratio of magnesium to chlorine atoms, while MgCl2 is magnesium chloride with a 1:2 ratio of magnesium to chlorine atoms. This means that MgCl has one chlorine atom for every magnesium atom, while MgCl2 has two chlorine atoms for every magnesium atom.
What substances are in Magnesium chloride?
Magnesium chloride is composed of magnesium and chlorine atoms. It is a mineral salt commonly used as a supplement to increase magnesium levels in the body.
