For each of the solvents below, choose the solute that will dissolve to a greater extent at room temp.
Solvent ♥ Solute Choices
Water (H2O) ♥ CHCl3 or CCl4
Ethanol (C2H5OH) ♥KOH or BBr3
Methaol (CH3OH) ♥ BrF3 or SbF5
Pentane (C5H12) ♥ SF4 or SF6
Propanol (C3H7OH) ♥ C6H14 or H2O
If you have the answer PLEASE PLEASE tell me how you got it!? thanks! ♥

the basic solubility rule is "like dissolves like"
1) CH3Cl has some polarity and will dissolve more in polar water than nonpolar CCl4
2) KOH is ionic and will dissolve more in polar ethanol than nonpolar BBr3
3) BrF3 has some polarity and will dissolve more in polar methanol than nonpolar SbF5
4) SF6 is nonpolar and will dissolve more in nonpolar pentane than slightly polar SF4
5) H2O is polar and will dissolve more in polar propanol than nonpolar C6H14
