Bronze mug loses it shine when kept in open environment .why?
Answers
Bronze, just like any other metal, has the tendency to tarnish or rust when reacts with oxygen present in the atmosphere. Our atmosphere contains a big amount of oxygen as vapor, which can easily react with the Bronze metal and rust it over the period of time.
The process of rusting of metals in presence of oxygen and humidity is termed as oxidation reaction. Another thing that you need to keep in mind is that Bronze is also highly reactive to oxygen in the atmosphere. This reaction results in the formation of green coating on the top layer of Bronze leading it to the formation of tan layer.
Answer:
Bronze mug loses it shine when kept in open environment because of corrosion.
Explanation:
Bronze is a metal alloy of copper and tin. Here both metals are more reactive and react with atmospheric oxygen and moisture to form metal oxide. The metal oxide of copper metal is little green and red color.
That decolorize the metal utensil and bronze mug loses it shine when kept in open environment. This process is called as corrosion that can be defined as the process of formation of metal oxide from the reaction of oxygen and metal.
