Answer 2

CORROSION:-

Corrosion is a natural process that converts a refined metal into a more chemically-stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually a metal) by chemical and/or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion

RANCIDITY:-

Rancidification is the process of complete or incomplete oxidation or hydrolysis of fats and oils when exposed to air, light, or moisture or by bacterial action, resulting in unpleasant taste and odor. Specifically, it is the hydrolysis or autoxidation of fats into short-chain aldehydes and ketones, which are objectionable in taste and odor.

SOME OTHER INFORMATION ABOUT CORROSION:-

1. TO PREDICT THE CORROSION WE SHOULD SEE THE SUBSTANCE ON WHICH,REDDISH LAYER IS FORMED OR NOT.
2. THE CORROSION OCCURS DUE TO ATMOSPHERIC OXYGEN AND OTHER COMPONENTS

SOME OTHER INFORMATION ABOUT RANCIDITY:-

1. RANCIDITY OCCURS WHEN A METAL LIKE OIL,PICKLE ETC.ARE KEPT AT OPEN PLACES
2. DUE TO WHICH THE SUBSTANCE GET OXIDIZED AND THE TASTE AND SMELL OF SUBSTANCE CHANGES

PRECAUTIONS:-

• THE SUBSTANCE LIKE OIL AND PICKLE SHOULD KEPT IN AIR TIGHT CONTAINER.
• FOR CORROSION VARIOUS METHOD LIKE GALVANIZING,TINNING,ELECTROPLATING IS DONE.
