This mild polarity of ozone greatly enhances the solubility of the molecule in a polar solvent like water. At 161 K (−112 °C; −170 °F), it condenses to form a dark blue liquid. Ozone is more soluble in n-decane than in water (Bin, 2006), and thus it is likely that aqueous ozone molecules partitioned into the n-decane phase reacting with fluorescence tracer. 6.Potential fire hazards and toxicity issues associated with ozone generation. Ozone is slightly soluble in water, and much more soluble in inert nonpolar solvents such as carbon tetrachloride (CCl 4) or fluorocarbons, where it forms a blue solution. 5.Ozone is less soluble in water, compared to chlorine, and, therefore, special mixing techniques are needed. Important tool: ORP Monitoring. The value of R t in a pH range from 2 to 6 is 0.3 ± 0.1. Learn More about ozone water treatment and other applications. Ozone is not very soluble in water and is typically dissolved using a venture which relies on intimate air / water contact under very high turbulence or a diffuser which breaks the gas into very tiny bubbles which are allowed to be in contact with the water for an extended period of time. Ozone is a colourless or pale blue gas, slightly soluble in water and much more soluble in inert non-polar solvents such as carbon tetrachloride or fluorocarbons, in which it forms a blue solution. If you look at the molecular structure of ozone below, you can see that it is polar. Coefficients of ozone solubility R t at pH values ranging from 0.1 to 11 are defined. Solubility guidelines for ionic compounds in water - Guidelines or solubility rules to predict whether or not a given ionic compound is soluble in water at room temperature Solubility product constants - The equilibrium constant, Ksp, for aqueous solutions of ionic compounds at 25°C. It is present in low concentrations throughout the Earth’s atmosphere. Ozone is formed from O 2 by the action of ultraviolet light and also atmospheric electrical discharges. I can't find anything that directly says why... My guess is that due to the oxygens double bond which requires a large amount of energy to break it doesn't readily react with other molecules and thus is more difficult to dissolve in water. For three marks I have to explain why ozone is considerably more soluble in water the oxygen. Diatomic oxygen is non-polar.
