Do Acidic Solutions Have More Hydrogen Ions
On the amount of hydrogen ions in acid
It is said that all acids contain hydrogen ions. But is this true?
I have heard that various sages have talked about physical properties, and there are many investigations into the quality of acid. The reason why acid is acidic is due to the dissociation of water, which generates hydrogen ions. Looking at common acids, such as hydrochloric acid and sulfuric acid, when they enter water, they can quickly dissociate, causing the number of hydrogen ions in water to increase sharply.
In water, there is a weak dissociation, generating a small amount of hydrogen ions and hydroxide ions, and the two are in balance. However, when the acid enters it, the molecules of the acid dissociate, and additional hydrogen ions are generated, breaking this balance, so that the amount of hydrogen ions far exceeds that of hydroxide ions. Therefore, the acid is acidic, which is also a sign of its multi-hydrogen ions.
There are experiments as evidence. It is tested with an acid-base indicator, and it changes color when exposed to acid. This is because of the effect of hydrogen ions and indicators. And measured by electrodes, the acid is conductive, because there are movable ions in it, and hydrogen ions are also important for conducting electricity. This shows the abundance of hydrogen ions in the acid.
However, there are also doubts and ask: "Are all acids multi-hydrogen ions?" Those with weak acids only dissociate in a small part in water, and the number of hydrogen ions is actually inferior to those of strong acids. However, although it is less, it is still more than that of pure water.
In summary, acid solutions probably contain more hydrogen ions than other common solutions, which is the nature of acid solutions. Although there are differences in strength, the amount of hydrogen ions is different, but they are all characterized by multiple hydrogen ions.
