Results of aluminum electrochemical corrosion experiments
Thread Content
I recently conducted a chemical experiment as follows: I filled a cup with tap water, then placed both ordinary aluminum foil and hydrophilic aluminum foil into the water, along with a copper tube, and observed it daily Guess what the result was? Results will be given tomorrow :):lol
Check if your copper tube is connected to him; is the hydrophilic aluminum foil gone?
Can the original poster reveal the answer? I don’t know
First, the hydrophilic aluminum foil is gone, then the regular aluminum foil is gone – so what can be plated on copper?
I’m sorry, everyone. I’ve been very busy these past few days and didn’t have time to come here; I just remembered today and rushed over to provide the answer. In my experiments, I observed that ordinary aluminum foil suffered significant corrosion; by stirring the water, many flocculent substances could be seen, which were the result of the aluminum’s corrosion.
This corrosion is actually electrochemical corrosion
I also conducted an experiment using pure water; guess what the result was?
Or we could discuss it as well; after all, I used to keep researching the issue of aluminum corrosion, and I’ve finally figured it out now.
What is the answer in purified water? It’s probably the same, right?
In pure water, aluminum does not corrode at all.
The flocculent substance is AL(OH)3; in fact, there is another solid product called ALO(OH)
