Strontium, Sr, is a metal that forms an ionic chloride $SrC{l_2}$.
Sulphur, S, is a non-metal that forms a covalent chloride $SC{l_2}$.
Which compound is likely to have the higher melting point (m.p.) and which is more soluble in water?
higher m.p.: $SrC{l_2}$ / more soluble in water: $SrC{l_2}$
2 )
higher m.p.: $SrC{l_2}$ / more soluble in water: $SC{l_2}$
3 )
higher m.p.: $SC{l_2}$ / more soluble in water: $SrC{l_2}$
4 )
higher m.p.: $SC{l_2}$ / more soluble in water: $SC{l_2}$
