I want to make O2- saturated 0.5M H2SO4 at 50C for the potentiodynamic polarisation study of Titanium metal. What is the optimum purging rate and time to obtained saturation?
Opposit problem - removing oxygen is purging by Ar for 20-30 min. Flow is "not much boiling". Water surface is mostly calm. Get rid of oxygen is much more difficult than saturating by oxygen. Thus, I think saturating is about 5 min - 10 min.
