define corrosion and rencidity with prevention
Answers
Explanation:
#Corrosion is defined as the process in which metal with atmospheric moisture and chemicals resulting in the formation of rust. Following is an example of rust or corrosion that takes place on the iron:
2Fe+3H2OrightarrowFe2O3+3H2
#Rancidity is a condition in which the substance with oil and fats get oxidized when they are exposed to air. A substance is said to be rancid when there is a change in smell, taste, and colour. An example of rancidity is when a chips pack is exposed to atmospheric air which results in a change in taste and odor.
#prevention from corrosion
1)painting the surface
2)Oiling the surface
3)powder coating
4)galvanizing- process of coating zinc which acts as a 5)protective layer
#prevention from Rancidity
1)storing them in airtight containers
2)keeping them in refrigerator
3)using nitrogen gas for storing them in packets
4)also adding antioxidants
I hope it is helpful to you......
thankyou
Answer:
Corrosion-Corrosion is a process where the metal corrodes. Corrosion is a natural process and in the presence of a moist atmosphere, chemically active metals get corroded. Corrosion is a process where the water or the moisture on the surface of the metal oxidizes with the atmospheric oxygen, it is an oxidation reaction.
Rancidity-Spoilage of food because of oxidation of fats present in them is called rancidity. Rancidity causes the food to smell and taste unpleasant
Explanation:
1) methods to prevent corrosion
Metal Type. One simple way to prevent corrosion is to use a corrosion resistant metal such as aluminum or stainless steel. ...
Protective Coatings. The application of a paint coating is a cost-effective way of preventing corrosion. ...
Environmental Measures. ...
Sacrificial Coatings. ...
Corrosion Inhibitors. ...
Design Modification.
2)Rancidity can be prevented using the following methods:
Adding antioxidants (substances which prevent oxidation) to food.
Storing food in airtight containers to slow the process of rancidification.
Refrigerating food also helps to slow down rancidification.
Replacing oxygen in the containers with another gas.
