Do acids donate hydrogen ions
On whether an acid donates hydrogen ions
I have heard all the wise people talk about the characteristics of acids, and they have expressed their opinions on the question of "whether an acid donates hydrogen ions".
Or: Acids must have the ability to donate hydrogen ions. Look at all common acids, hydrochloric acid, sulfuric acid, etc., in aqueous solutions, they can dissociate and release hydrogen ions. Its nature is active, and in case of alkali, it will combine with hydroxide ions to form water and salts. This is the general nature of acids, based on the donation of hydrogen ions. In solution, due to the characteristics of its own structure, the binding force of hydrogen atoms and other atoms is different. When encountering solvents such as water, hydrogen atoms are easy to leave in an ionic state. This is also the characterization of acid donating hydrogen ions.
However, there are also those who disagree: the concept of acid cannot be generalized just by donating hydrogen ions. The definition of ancient acids is not as clear as it is today, and the substances in the world are complex and changeable in nature. Although most common acids have this property, they cannot be generalized. For example, some organic acids have complex structures, and under specific conditions, the dissociation of hydrogen ions is not easy, or special catalysis and environment are required to appear like donating hydrogen ions. And in non-aqueous systems, the behavior of acids is very different from that in aqueous solutions. The definition and characteristics of acids should be considered separately. Aneng covers it with the words "donating hydrogen ions"?
To sum up, the relationship between acid and hydrogen ions, although the donation of hydrogen ions is an important characteristic of common acids, it seems inappropriate to use it as the absolute definition of acid. Everything in the world changes endlessly, and scientific principles need to be continuously explored and improved in order to achieve accurate and comprehensive understanding.
