New cards

whats the effect of ionic CHARGE on lattice enthalpy

  • ionic charge increases

  • attraction between ions increase

  • lattice energy becomes more negative

  • melting point increases

2
New cards

whats the effect of ionic RADIUS on lattice enthalpy

  • ionic radius increases

  • attraction between ions decreases

  • lattice enthalpy less negative

  • melting point decreases

3
New cards

whats the effect of ionic CHARGE on hydration enthalpy

  • ionic charge increases

  • attraction with water molecules increases

  • hydration energy becomes more negative

4
New cards

whats the effect of ionic radius on hydration enthalpy

  • ionic radius creases

  • attraction between ions and water molecules decrease

  • hydration energy becomes less negative
