What is the most common and least expensive method for commercial production of O2?

	Electrolysis of water
	Fractional distillation of air
	Chemical decomposition of sodium chlorate
	Physical separation by molecular sieves

Solutions

Expert Solution

The most commonest way for production of commericial oxygen is fractional distillation of air ( Fractional distillation uses the different boiling points of the main elements of air. As the liquid air is heated, the elements change from liquid to gas and separate from one another), because

production of 02 using electrolyis of water requires huge electricity and expensive electrodes

chemical decomposition of chlorate is also expensice and it is used in emegengy oxygen in aircraft it is generates very pure oxygen

You purchase an expensive O2 microelectrode and use it to measure the dissolved O2 profile in a sediment core that you obtained from Long Island Sound. You find that the O2 concentration on the water-sediment interface is 240 mol/L, and it sharply drops to 40 mol/L at 0.2 cm deep in the sediment. If the corresponding dissolved O2 diffusion coefficient (Ds) in porewater seawater is 1.0 × 10-5 cm2 /s. The porosity () of sediment is approximately constant over the...
