Question : Crude oil is sometimes termed sweet because it is:
Option 1: sweet in taste due to dissolved sugars
Option 2: mild sweet due to low sulphur content
Option 3: less acidic
Option 4: less alkaline
Correct Answer: mild sweet due to low sulphur content
Solution : The correct option is mild sweet due to low sulphur content .
Sweet crude oil is a type of oil that contains only 1% sulphur. The term "sweet" is used to describe its mild and pleasant smell, unlike sour crude, which has a higher sulphur content and a less pleasant odour. Refineries prefer sweet crude oil because it requires less processing to remove sulphur impurities, resulting in cleaner end products.
