Verified step by step guidance1
Identify the type of compound: H₂S is a binary compound consisting of hydrogen and sulfur.
Recognize that H₂S is a binary acid. Binary acids are composed of hydrogen and one other nonmetal element.
For binary acids, the naming convention is to use the prefix 'hydro-' followed by the root of the nonmetal's name and the suffix '-ic acid'.
Determine the root name of the nonmetal: The nonmetal in H₂S is sulfur, so the root is 'sulfur'.
Combine the prefix, root, and suffix to form the name: 'hydro-' + 'sulfur' + '-ic acid' results in 'hydrosulfuric acid'.
