The lower curves represent twoexperiments with the usual amount of oxygen present. Theelectrolyte was prepared by adding sulphuric acid to distilledwater without any special precautions either to exclude the air orto aerate the solution. In experiments 38 and 39 represented bythe two upper curves, the electrolyte was saturated with oxygenby rapidly bubbling oxygen through the electrolyte during theexperiment. The curves show that increasing the amount ofoxygen in the solution accelerates the speed of corrosion verymaterially, the loss of weight in 24 hours being about twice asgreat when oxygen was passed through the electrolyte, as whenoxygen is supplied by diffusion only. It follows from this thatthe rate of corrosion in any acid solution will depend on theamount of aeration to which the solution is APPARATUS TYPE I
