Question

In a mixture of kerosene and water, kerosene forms the:

• A. Lower layer
• B. Upper layer
• C. It mixes with water and forms no layer
• D. Data insufficient

Answer 1

Answer: (B)

Upper layer

When two liquids do not mix, they form two separate layers and are known as immiscible liquids. These two liquids can be separated by using a separating funnel. It will separate the immiscible liquids into two distinct layers depending on their densities. The heavier liquid forms the lower layer while the lighter one forms the upper layer. Kerosene has lower density than water and hence forms the upper layer.
