Electrolysis-related old news

Can news be old.... *pondering* Anyway, here's the news (that are old)...

Engineers Forge Greener Path To Iron Production

Basically, researchers at MIT are studying the viability of extracting iron through electrolysis.

Q1. Why do we not use electrolysis to extract iron at the present?
Q2. Why do the article say "Unlike aluminum smelting, however, MOE is carbon-free."? Is C used in aluminium extraction?
Q3. Do you think that electrolysis of iron oxide is really carbon-free?

Current Research Offers Hope For Liver Cancer Patients

If you think this article is out of place, then you are wrong. Researchers at Adelaide University are trying to kill tumor cells using electrolysis.

Two electrodes are used to treat a tumour in the left lobe of a patient's liver. Gas from the electrolysis forms a cluster of bubbles around one electrode. The yellow structure is the divided ligamentum teres.

Q4. What gas do you think is formed at the electrode?
Q5. What are some problems you think we might face with this technology?

So here's the fifth application of electrolysis =P

Please submit your answer to the comments section and not the tag-board. Thanks.

Electrolysis

Yoz!

Here's the learning objectives for the topic on Electrolysis. Mug hard for the test next week. You will be rewarded for your hardwork.

When you are tired, you can try this interactive 'game'. Test you on the conceptual understanding. http://www.edukate.net/ed1_files/electrolysis.html
