Acid Gives Hydrogen
"Acid Hydrogen Generation"
Acids are very different from ordinary things. Among all kinds of changes, every one can produce hydrogen. Looking at all kinds of acids, when they encounter active metals, such as zinc and iron, they react immediately. Active metals enter the acid, like a fish in water, and in a moment, bubbles gush out. This is the escape of hydrogen gas.
The reason is that acids in water can dissociate hydrogen ions, active metals are active and easy to lose electrons. The lost electrons combine with the hydrogen ions of the acid to form hydrogen gas. This change is not visible to the naked eye, but it is subtle and contains the mystery of nature.
The hydrogen generation of acids is not unique to metals. In the case of specific compounds, this change can also occur. If it reacts with certain metal oxides, acids react with them, in addition to forming salts and water, and occasionally hydrogen is produced.
From this perspective, acids have the property of generating hydrogen, which is an important characteristic of them. For all kinds of changes in chemistry, this property is often the key and has a far-reaching impact. To understand this, the properties of acids and the laws of chemical reactions can be obtained in detail, and it is also very helpful for learning the way of chemistry.
