On the formula of hydrosulfide acid
The key to chemistry is to seek the structure of the substance, and to show that its formula is the first. Hydrosulfide acid is an acid combined with sulfur and hydrogen.
The formula seeks to look at the properties of the two first. Hydrogen, the active element, often shows positive monovalent; sulfur, the polyvalent element, in hydrosulfide acid, often shows negative divalent. According to the valence rule, the sum of positive and negative valence is zero, so the combination of hydrogen two and sulfur is $H_2S $.
This formula is not a combination of elements, which has a deeper meaning. In terms of structure, diatomic hydrogen is covalently bonded to sulfur atoms to form a V-shaped structure. This structure is related to its properties, such as solubility, acidity, etc.
In water, hydrogen sulfide acid can be ionized, releasing hydrogen ions, and showing acidity. According to its formula $H_2S $, its ionization state can be deduced. Initial ionization, $H_2S\ rightleftharpoons H ^ ++ HS ^ - $; secondary ionization, $HS ^ -\ rightleftharpoons H ^ ++ S ^ {2 - }$ ， However, secondary ionization is difficult and the degree is quite weak.
From the perspective of the reaction, according to its formula, it can be seen that it responds to other things. In case of alkali, hydrogen ions and hydroxide ions combine into water, according to the amount of hydrogen in $H_2S $, the ratio to the alkali can be determined.
To be important, the formula of hydrogen sulfide acid is $H_2S $, which is the basis for explaining its properties and analyzing its response. It is also crucial for chemical exploration.
