Question
in producing h2 gas why magnesium is used
Answers
GPT 3.5
Magnesium is commonly used in the production of hydrogen gas (H2) because of its high reactivity and ability to easily liberate hydrogen from water or acids. When magnesium reacts with an acid or water, it undergoes a redox reaction, where magnesium atoms lose electrons and are oxidized, ultimately producing hydrogen gas.
The reaction can be represented by the following chemical equation:
Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)
In this reaction, magnesium (Mg) reacts with hydrochloric acid (HCl) to form magnesium chloride (MgCl2) and hydrogen gas (H2). The hydrogen gas is then collected and used for various applications.
Magnesium is chosen for this reaction because it is relatively inexpensive, readily available, and has a high hydrogen yield. Additionally, magnesium has a high reactivity due to its low ionization energy and ability to readily release electrons, making it efficient for hydrogen gas production.
