Whichof 0.1M 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 solution being smaller size than `K^(+)` ion and `H^(+)` ion have greater MOBILITY than `K^(+)` ion. Which mobility of the ion increase, conductivity of that ions also increases. Hence, 0.1 M HCl solution has greater molar conductance than 0.1 M KCl solution. |
