Answer 2

When pt and co are electrically connected, which one gets corroded?

Explanation:

• Carbon monoxide (CO) gas streams can cause corrosion and contamination of sensitive processes, like catalysts and semiconductor fabs, when exposed to metals that readily form oxides The resulting corrosion formation is called a carbonyl group.
• So, co gets corroded.
