Guida verificata passo dopo passo1
Understand that hydrosulfuric acid is a common name for a specific binary acid composed of hydrogen and sulfur.
Recall that binary acids consist of hydrogen and one other nonmetal element, without oxygen atoms in their formula.
Recognize that hydrosulfuric acid corresponds to hydrogen sulfide dissolved in water, which has the chemical formula \(\mathrm{H_2S}\).
Distinguish hydrosulfuric acid from sulfurous acid (\(\mathrm{H_2SO_3}\)) and sulfuric acid (\(\mathrm{H_2SO_4}\)), which both contain oxygen atoms and are oxyacids, not hydrosulfuric acid.
Conclude that the correct chemical formula for hydrosulfuric acid is \(\mathrm{H_2S}\).
