Question

select the correct answer.
what is the name of h₂s?
a. sulfuric acid
b. sulfurous acid
c. hydrosulfurous acid
d. hydrosulfuric acid

Explanation:

• Sulfuric acid is \(H_2SO_4\).
• Sulfurous acid is \(H_2SO_3\).
• Hydrosulfurous acid is \(H_2S_2O_4\).
• For binary acids (acids composed of hydrogen and one other non - metal element), the naming rule is “hydro - (non - metal root) - ic acid”. Here, the non - metal is sulfur (root “sulfur”), so \(H_2S\) is named hydrosulfuric acid.

Answer:

D. hydrosulfuric acid
