Which of 0.1 M HCl and 0.1 M KCl do you expect to have greater molar conductance and why? |
|
Answer» Solution :Compare to 0.1 M HCl and 0.1 M KCl, 0.1 M HCl has greater molar conductance. Molar conductance of `"0.1 M HCl"=39.132xx10^(-3)"Sm"^(2)"mol"^(-1)`. Molar conductance of `"0.1 M KCl"=12.896xx10^(-3)"Sm"^(2)"mol"^(-1)`. Because, `H^(+)` ion in aqueous being smaller SIZE than `K^(+)` ion and `H^(+)` ion have greater MOBILITY than `K^(+)` ion. when mobility of the ion increases, conductivity of that IONS also increases. HENCE, `"0.1 M HCl"` solution has greater molar conductance than `"0.1 M KCl"` solution. |
