Conjugate Base of Hydrogen Sulfide

The conjugated base of hydrogen sulfide ($H_2S $) is the hydrogen sulfide ion ($HS ^ - $). The relevant chemical principles are described below in classical Chinese:

Hydrogen sulfide can be dissociated in water. Its protons ($H ^ + $) are easy to leave, and the remaining particles, namely hydrogen sulfide ions, are the conjugated bases of hydrogen sulfide.

When hydrogen sulfide is in solution and encounters alkaline substances, the hydrogen protons in its molecules escape. At this time, hydrogen sulfide loses a proton and forms hydrogen sulfide ions. This hydrogen sulfide ion is negatively charged due to the electrons left behind by hydrogen sulfide. It can combine with protons and return to the state of hydrogen sulfide; it can also lose protons under certain circumstances, and then convert into sulfur ions ($S ^ {2 - }$)。 This is due to the principle of acid-base conjugation. Between chemical changes, substances change each other according to this rule.
