ionic compound aqueous cations and anions
covalent aqueous covalent compound solution
1) Ionic compounds; acqueous cations and aqueous anions
2) covalent compounds; acqueous covalent compounds
ionic compound will produce aqueous anion and aqueous cations
covalent compound will form aqueous covalent compound
Ionic compounds dissociate into ions in water. For example, NaCl will dissociate into Na+ and CL-. This gives the solution conductivity. Covalent compounds however, do not dissociate into ions in water. In fact, only polar covalent compounds are soluble in water. Like dissolves like. Water is polar, so it will dissolve polar covalent comounds. Most covalent compounds, however, are non polar and don't dissolve. So the difference is that ionic compounds dissolve and covalent do not.

An ionic molecular solid AX has a molecular weight 250 g/mol is face centered cubic with regard to the anions, X, which have a radius of 300 pm. The cations, A+, have radius 200 pm and are found octahedral interstitial spaces. The edge of each unit cell is as long as the diameter of 1 cation and 1 anion. When 25 grams of AX (as described above) is dissolved into 500 grams of water at 293.15 K 41.36 kJ of...
