Part 4. Optimizing Conditions
(Tere page 17) We have determined that the optimal voltage for
the Pt and Pb variants is the 6 V setting on the DC power supply.
Higher voltages give similar results to the 6 V setting. Lower
give poorer results.
Also, the actual
for each setting is:
Actual (Pt/C) Actual (Pb/C)
"useful lifetime of the ozone generators by letting them run and
ozone production every hour. She found that for Pt/C, the
lasts about 8 hours (page 16) and the Pb/C generator about 4 hrs (page
Tere also investigated the
of the sulfuric acid concentration. She used 3 M, 4 M, 5 M and 6
M. We measured gas production (in mL) and ozone production (by
with excess KI and titration with thiosulfate). The ratio of
of thiosulfate to volume of gas production is proportional to the
ozone in the produced gas. Results do not indicate an ideal
The ratio remained quite similar regardless of the concentration.
