Question

which of the following is a molecular compound that produces h⁺ ions when dissolved in water? view available hint(s) hg(no₃)₂ nac₂h₃o₂ ch₄ h₂so₄

Explanation:

To determine the molecular compound that produces \( H^+ \) ions in water, we analyze each option:

• \( Hg(NO_3)_2 \): Ionic compound (metal + polyatomic ion), dissociates into \( Hg^{2+} \) and \( NO_3^- \), no \( H^+ \).
• \( NaC_2H_3O_2 \): Ionic (sodium salt), dissociates into \( Na^+ \) and \( C_2H_3O_2^- \), no \( H^+ \).
• \( CH_4 \): Molecular, but non - polar, does not dissociate in water to produce \( H^+ \).
• \( H_2SO_4 \): Molecular (covalent bonds in structure), is a strong acid. In water, it dissociates as \( H_2SO_4

ightarrow 2H^+ + SO_4^{2 - } \), producing \( H^+ \) ions.

Answer:

\( \boldsymbol{H_2SO_4} \) (the option corresponding to \( H_2SO_4 \))
