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.
