Prevent rusting by connecting to electricity?

AI Thread Summary
Connecting a more reactive metal to a water pipe can prevent rusting through a process known as cathodic protection. This method involves using a more reactive metal to corrode instead of the pipe, effectively protecting it. The discussion also explores the idea of using an electric source to achieve similar results through electrolysis, which would liberate oxygen from the metal and further inhibit rust formation. This concept aligns with anodic protection, where an external electric current is applied to enhance corrosion resistance.

My textbook says that we may prevent a water pipe from rusting by connecting a more reactive metal to it with a wire... so i was thinking that can we prevent it from rusting by just simply connecting it to an electric source since electricity is a running electron flow...

yeah that would work because you would be liberating the oxygen from the metal through electrolysis, so it shouldn't rust
 
See 'anodic protection' as in the Wikipedia.

Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'

I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...

I tracks prices of Pt, Pd, Ru, Ir and Ru. Of the 5 metals, rhodium (Rh) is the most expensive. A year ago, Rh and Ir...
