The scale of a chemical balance… | Chemistry

Question 1 Report

The scale of a chemical balance is made of iron plate and coated with copper electrolytically because

iron is less susceptible to corrosion than copper

copper is twice as less susceptitible to corrosion as iron

copper is less susceptible to corrosion than iron

copper and iron are equally susceptible to corrosion

Answer Details

The reason why the scale of a chemical balance is made of an iron plate and coated with copper electrolytically is that copper is less susceptible to corrosion than iron. When iron is exposed to air and moisture, it reacts with oxygen and forms iron oxide, which is commonly known as rust. Rust can weaken and damage the iron, which can ultimately affect the accuracy of the balance. Copper, on the other hand, is more resistant to corrosion and therefore is a better choice for coating the iron plate of the scale. This ensures that the scale remains accurate and can be used for a longer period of time.
