Which of the following is NOT a method of rust prevention? A) Galvanizing B) Painting C) Exposing to saltwater

A

C) Exposing to saltwater

22
Q

What role does moisture play in the formation of rust?

A

Moisture acts as an electrolyte, facilitating the electrochemical reactions that lead to rust.

23
Q

metal chloride + hydrogen
26
what reacts with cold water, steam and acid
potassium, sodium, calcium and magnesium
27
potassium and sodium reaction
- reacts violently with cold water - explode with steam - explode with dilute hcl
28
calcium reaction
- reacts slowly with cold water - explodes with steam - react violently with hcl
29
magnesium reaction
- reacts slowly with cold water - reacts violently with steam -react rapidly with hcl
30
zinc reaction
- no reaction with cold water - react readily with steam - react fast with hcl
31
iron reaction
- no reaction with cold water - reacts slowly with steam - reacts slowly with hcl
32
lead copper silver gold reaction
- no reaction with cold water no reaction with steam - no reaction with hcl
