Interpretation:
To determine thename of ionic compound formed by ionic species Mg2+.
Concept Introduction:
Ionic compound is formed by the combination of ions. In which one is metal and one of them is nonmetal. Nonmetal formed anion and metal formed the cation.
Ions are formed by loss or gain of an electron. If an atom gain the electron it will carry positive charge and if it lose the electron it will carry the positive charge. The electron present in the outermost shell of an atom is mostly responsible for formation of ions. If the number of proton is less than number of electron the species is anionic and if the number of proton is higher than number of electron the species if cationic.

This risk is minimized with the use of low molecular weight heparins (LMWH), therefore it is desirable to separate LMWH from higher molecular weight heparins. The method of choice to do this is molecular exclusion chromatography. Below is a chromatogram from a molecular exclusion chromatographic run. Peaks ranging from A to J are clearly distinguishable. The heparin mixture that was analyzed had anywhere from 6 to 30 repeat units of monomer (where the heparin with 30 repeat units would be roughly five times the size of the heparin with six repeat units). a.
