Which of the following equimolar solutions has the highest conductivity?
\(H_2SO{_4(aq)}\)
\(NaOH{_(aq)}\)
\(H_2CO{_3(aq)}\)
\(CH_3COOH{_4(aq)}\)
Giải thích
\(H_2SO_4\)(aq) is a strong acid that dissociates into two hydrogen ions (H+) and one sulfate ion \(SO4^{2-}\) when dissolved in water. This leads to a higher concentration of ions in the solution, resulting in higher conductivity.
