enthalpies of solution and Hydration

whah happens to ionic salts dissoolved in water

the lattice breaks up into ions , interact with polat water molecules to form hydrated ions

what forces hold the hydrated ions

dipole-dipole forces

what is enthalpy of solution

the enthalpy charge when 1 mole of a solute , in its standard stat dissolves in water to form aqueos ions

is enthalpy of solution exo or endo

exo or endo

process of ionic lattice breaks apart as endothermic

attraction of ion to polar water molecules exothermic

what is enthalpy of hydration

the enthalpy change when 1 mole of gasesou ions are converted into aqueos ions

enthalpy of hydration exo or endo

gaseso ions - no bonds/IMF

Aqueos ions , ion- dipole focesc between aqueos ions and polar water

so exo

what factoes depend how exothermic enthalpy of hydration

depends on strength of ion-dipole forces

bigger charge , lower size , stronger ion-dipole forces , more exothermic
