« on: April 18, 2020, 06:38:19 PM »
Hi.. Im doing a university paper on corrosiv chemicals when there applyed to metal, and would like to demonstrate a practical with the class.. The metals i will be attempting to corrode will be! 1. Galvanize steel 2. Steel 3. Iron 4. Aluminium 5. Copper. I will be needing to use more house hold chemicals E.G. Bleach, fertilizer.. Stuff like that! i know bleach will corrode galvanize steel! And ive heard from a friend that copper sulphate & phosphric acid cu3(Po4)2 will corrode most metals is this viable?? If so which chemicals would i be best to use? TIA

Under household compounds, you have acids to remove scale, bases to decompose organic leftovers in drains.

"Aluminium" isn't accurate enough. Depending on the alloy, the corrosion behaviour will differ a lot. "Iron" is ambiguous too: it could be pure iron or cast iron.

Don't mix bleach with other compounds.
