0.10 mol dm-3 NaCI conducts electricity better than 0.10 mol dm-3 CH3COOH because the solution of NaCI
contains more ions
is neutral to litmus
has a lower molar mass
has a higher pH
설명
0.10 mol \(dm^{-3}\) NaCI conducts electricity better than 0.10 mol \(dm^{-3}\) \(CH_3COOH\) because the solution of NaCI contains more ions. When an ionic compound like NaCI dissolves in water, it dissociates into its component ions, \(Na^+\) and \(Cl^{-}\)
