Answer #1

H2SO4 is strong acid it dissociate completely in water as follows

H2SO4 -----> H+ + HSO4-

When H2SO4 dissolved in water H+ ions of H2SO4 binds with surrounding polar water molecules therefore H2SO4 is miscible with water at all concentrations

C2H5OH is also miscible with water at all concentrations because it forms interhydrogen bonding with water

CH2Cl2 is less soluble in water because it does not form hydrogen bond with water approximately 13 g/L is miscible with water

C6H5NH3CL is phenylammonium chloride is salt that is polar compound since water is also polar therefore phenylammonium chloride dissolve in water to the extent of 36 Gram/liter

terefore CH2Cl2 is least soluble
