Which of the ions in the table below would have the largest value of enthalpy of hydration?
Ionic radius in nm Charge of ion

Options

A. `{:("Ionic radius in nm " ,"Charge of ion"),(0.0065,+2):}`
B. `{:("Ionic radius in nm " ,"Charge of ion"),(0.095,+1):}`
C. `{:("Ionic radius in nm " ,"Charge of ion"),(0.135,+2):}`
D. `{:("Ionic radius in nm " ,"Charge of ion"),(0.169,+1):}`

Answer

A

Explanation

Smaller the size of the ion andgreater the charge on the ion,greater is the enthalpy of hydration.
