The ions are separated from each other, and are free to move randomly through the solution, surrounded by a crowd of water molecules. d) the randomness or entropy of the system increases greatly. Water is a polar protic solvent. First, find moles of C 2 H 5 OH: 50.0 ml x 0.789 g / mol x 1 mol C 2 H 5 OH / 46.1 g = 0.8557 mols C 2 H 5 OH Next, convert ml of H 2 O to kg of H 2 O (assume a density of 1.0 g/ml): 112.7 ml x 1.0 g/ml x 1 kg / 1000 g = 0.1127 kg Finally, compute the molality: m = 0.8557 mols / 0.1127 kg m = 7.59 m (3 sig. What is the chemical equation for NH4OH dissolution in water. For this reason Ethanol molecules will spread out in the water (dissolve) and form a homogeneous solution. Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules. Screen capture done with Camtasia Studio 4.0. This is because C2H5OH has a polar OH bond that the water molecules like to hang around.

The reason so many covalent compounds do disassociate in water is that water is a highly polar solvent and therefore preferentially solvates ions (provides the driving force for the disassociation). The reasons are electrostatic in nature. The answer is that Ethanol is soluble in water. 10. Chapter 10: Properties of solutions Section 1: Basic concepts Section 2: Energies of solution formation Explanation for like dissolve like: Because the total enthalpy is too high, more energy is required to overcome the effects, thus impossible to form the solution. For alcohols with longer chains of carbon atoms, like CH3(CH2)9OH (Decanol) much of the molecule is nonpolar (or only very slightly polar) and the molecule will therefore be insoluble in water.
