Magnesium detection can use EDTA titrimetric method analysis. Because than aluminium magnesium alloy light, so it can be used in aviation, spaceflight. Another using magnesium oxide, to the nature can be used in the manufacture of many of pure metal reductant. Can also be used to flash, inspiratory, etc.
Determination of total hardness is water in calcium, magnesium ions, the total content available EDTA coordination titration:

Before the titration, EBT + M - EBT

(red),

The reaction: M + Y wish

End: M - EBT EBT + + Y wish

(red) (blue)

Titration to solution from red to blue, namely to finish.

Titration, Fe3 Al3 + +, such interference ion can be masking triethanolamine, Pb2 Cu2 +, Zn2 + +, weight of ion, usable KCN, Na2S mercaptoacetic acid or to cover.

Water hardness has a variety of methods, this experiment requirement to each liter Ca2 +, contained in Mg2 + amount (convert CaO said, the quality of mg, L - 1 unit.

According to the hydrocarbon magazine’s latest statistics show that by the end of 2010, by the end of March 10 vinyl producers, global rankings are as follows: first, the capacity for her company is 2296.5 tons/year, The second is the dow chemical, capacity for 857 tons/year, The third is sinopec, capacity of 728.5 tons/year, The fourth is lyondell Basel, capacity for 544 tons/year, The fifth is the shell, the capacity for 537 million tons/year, The sixth exxon mobil, capacity for 1087 tons/year, The seventh is the book company, capacity of 394.5 tons/year, The eighth, for the oil production 371.4 tons/year, Chemical company to 365.5 noirtier tons/year productivity ninth, Basf to 243 tons/year ranked tenth of capacity.

Many patients found themselves without their usual symptoms within a very short period of time, often within seven to twenty days of the beginning of treatment. When the ticker is struggling, the last thing any patient wants to do is take too much time determining what the best course of action might be. With such clear cut and obvious results no patient needs to wait more than a month to determine if positive changes are occurring. With such a rapid turn around time, patients feel rather confident that their health is under their control and that they have options that offer them immediate or near immediate feedback.

When faced with a serious heart condition having options such as EDTA chelation therapy allows patients a wider variety of choices. Those who are choosing to go with a treatment round of EDTA chelation therapy have found that their results are better than expected and much improved over the time they spend with their physician. Of course, a heart condition is serious business and no one should spend their time and energy on a treatment that offers little to no hope of improvement, which is why EDTA chelation therapy is becoming such a popular choice. Many patients want to do more than take daily medication for the rest of their lives and live in the face of open heart surgery.

Say well together

But what happened

Did I do something wrong
