Aircraft de-icing agents, such as propylene glycol [1,2- propanediol; CH3CH(OH)CH2OH;
Chapter 15, Problem 15.121(choose chapter or problem)
Aircraft de-icing agents, such as propylene glycol [1,2- propanediol; CH3CH(OH)CH2OH; d_1.036 g/mL], are used to remove ice and snow prior to winter flights, but their presence in runoff depletes O2 in natural waters. (a) Write a balanced equation for the complete oxidation of propylene glycol by O2. (b) What is the theoretical oxygen demand, in grams of O2 required per gram of propylene glycol oxidized? (c) What is the theoretical oxygen demand, in grams of O2 required per liter of solution, of 90.0% by volume aqueous propylene glycol?
