Question

7. Mustard oil and grease both are insoluble in water, but mustard oil floats whereas grease settles down, why?​

Answer 1

Answer:

Mustard oil does not mix well with water and forms a separate layer with water because it is an immiscible liquid

Answer 2

Even when you mix oil and watertogether they still separate. The oilalways floats to the top because it is less dense than water. Oil and waterdon't mix because water molecules are more attracted to each other than tooil molecules. Detergent molecules are attracted to both water and oil.
