Which of the following ion has highest molar conductivity at infinite ...
Molar conductivity of ions at infinite dilution in an aqueous solution depends on their size and charge. Smaller and highly charged ions have higher molar conductivity.
Explanation:
- The ion H+ is a small ion and has a very high charge density. Therefore, it has the highest molar conductivity at infinite dilution in an aqueous solution.
- F-, Cl-, and Br- are all larger ions than H+ and have lower charge densities. Therefore, they have lower molar conductivity than H+.
- Among F-, Cl-, and Br-, Br- is the largest ion and has the lowest charge density. Therefore, it has the lowest molar conductivity among the options given.
Hence, the correct answer is option 'D' (HO-).
