many ionic compounds do not just exist in a laboratory or in your chemistry homework sodium chloride is regular tape salt sodium chloride is added to some toothpaste to help strengthen tooth enamel ammonium nitrate can be used to fur life plants although their real life applications are very different they share a few Key Properties in this lesson we will turn it out the properties of ionic compounds that compounds have very high melting points and are brittle because of their 3D giant ionic lattice structure the strong electric static attractions holding the 3D lattice structure in place mean that is energy is required to overcome these attractions when we apply for it and breaks the regular repeating pattern of oppositely charged ion causing ions with like charges to come close to one another the ensuing repulsion breaks the lattice structure sodium chloride sodium fluoride and ammonium nitrate can all dissolve in water as we know or else we wouldn't be to flavor our soups brush our teeth or fertilizer plants most ionic compounds are soluble in water in water and ionic compound can dissociate into its ions so when we dissolve sodium chloride it will dissociate into sodium and chloride ions these ions become stabilized in water due to the polar nature of water you can see the sodium ions are stabilized by the negative dipole of water and the chloride ions are stabilized by the POS dipoles of water sulfation stabilizes the free floating ions and ionic compounds dissolve in water can conduct electricity this is another T property of ionic compounds this is made possible due to the presence of free putting ions we can dissolve copper II sulfate in water in a beaker add a few drops of sulfuric acid play sister copper and a strip of sink into the solution diesel act as electrodes using two alligator clips connect one one end of the mini light bulb and another strip to the other end to complete the circuit you will see that the light bulb up hence the solution conducts electricity following on the same idea Multan an ionic compound and also conduct electricity the lattice structure is broken at high temperatures and so the ions become free floating in summary ionic compounds have high melting points are brittle and can conduct electricity when dissolved in water or molten due to the presence of free floating ions
