Answer to Question #129818 in Organic Chemistry for Morgan

Question

Give two ionic equations representing the formation of the ions obtainable from hydrogen

Answer 1

A hydrogen ion is created when a hydrogen atom loses or gains an electron. A positively charged hydrogen ion (or proton) can readily combine with other particles and therefore is only seen isolated when it is in a gaseous state or a nearly particle-free space.^[1] Due to its extremely high charge density of approximately 2×10¹⁰ times that of a sodium ion, the bare hydrogen ion cannot exist freely in solution as it readily hydrates, i.e., bonds quickly.^[2] The hydrogen ion is recommended by IUPAC as a general term for all ions of hydrogen and its isotopes.^[3] Depending on the charge of the ion, two different classes can be distinguished: positively charged ions and negatively charged ions.

H₂ ----------------> 2H⁺ + 2e .

H + e -----------------> H^- .
