non polar solvents
 

will non-polar solvents dissolve only polar solute, only non-polar sovetes ionic solutes or all three

and can you explain why it would or wouldn't dissolve those three

"like dissolves like" meaning polar things dissolve polar things and non-polar things disolve non-polar things. That's why oil doesn't mix with water but salt does.

thanks that helps but how are ionic solutes different then non-polar or polar

Ionic compounds are always polar.

This is what happens
