it should be Dsorry for my poor English, I’m not from CanadaIn order to dissolve sth.these things will happen1. solvent – solvent attractions are broken down2. solute – solute attractions are broken down3. solute – solvent attractions are built upTo let this occursthe solute – solvent attraction should be the strongest force among solvent-solvent; solute-solute ; solute solvent or at least similar strengthAs water is a polar solventsth can dissolve in water should be able to form Hydrogen bond wif solute moleculessth which is polar are also can be slightly solublefor example carboxylic acid (-COOH) can form extensive hydrogen bond with water, it is soluble in water then.On the contrary, Alkane is neither polar nor hydrogen-bond-forming molecules, it do not dissolve in water.(this is the case of covalent compound——————–(ionic compoundall ionic compound are soluble in waterthere are mainly 5 steps for the dissolution processionic compounds adopt giant ionic structurecations and anions are alternatively held together by non-directional electrostatic force ( ionic bond)Water is a kind of polar molecule, there are permanent dipole moment acting on it. H atoms carry a slightly positive charge while O atoms carry slightly negative charge.attraction between H atoms in water molecules and anions in the ionic compound,attraction between O atoms in water molecules and cationsin the ionic compound are stronger than the ionic bond.Therefore, cations and anions are pulled away from the ionic lattice and dissolved in water————-Make a little conclusion for the concept1. ionic compound : cations <–ionic bond–> anions2. Water: H2O : H(slightly +ve) ; O(slightly -ve) 3. H2O’s O<–attraction–>cations <–ionic bond–> anions<–attraction–>H2O’s H 4. attraction > ionic bond5. structure of ionic compound is broken down!* finally product will be… =>H2O’s O<–attraction–>cations & anions<–attraction–>H2O’s H to sum upthe major factor is the solute-solvent attraction is strong enough => solublehope can helpMeteor from H.K....
