Solubility: Determine whether th Wy: Determine whether the following pairs of substances are soluble or insoluble. The first substance listed is the solute, and the second is the solvent. (A) CaSO4 in water [B] NaPO4 in water (C) PbCl2 in water [D) Mg(OH)2 in water [E] (NH4)2CO3 in water [F] Water (H2O) and hexane (C6H14) [G] Benzene (CH) and toluene (C Hs) [H] NaCl and benzene (C6H6)

Answer 1

Water is polar but hexane is non -polar so both are insoluble .

Benzene and toluene both are hydrophobic in nature so these two are missible .
