Solubility of Ionic bonds

Postby Norah Gidanian 3D » Sat Dec 12, 2020 10:16 am

Can someone explain why ionic bonds are soluble in water? Is it because the bonds are weaker because the electrons are being pulled to one side so it makes the bond weaker and easier to break apart in water?

The main idea of solubility is that the stronger the intermolecular forces between the solute and solvent, the greater the solubility. Since ion-dipole is a strong intermolecular force, ionic compounds are more easily able to dissolve in water. Also ,the ions will be stabilized when in water because the charge attracts either the positive or negative dipoles of the water. Hope this helps!

The partial charges of H2O (+ H and - O) are attracted to the partial charges of the ion (salt). For example, O - is attracted to Na + and H + is attracted to Cl -. These are ion dipole forces -- forces between the partial charge of a polar molecule (water) and the charge of an ion (Na or Cl). Ion dipole forces are considered strong and are capable of breaking apart the salt molecule.

I agree I think the easiest way to think about it is when it reacts with water the positive end of the water molecule with mix with the negative end of the molecule (and vice versa) and will pull the ionic compound apart.
