Question

experimental procedure: emulsification of lipids
label three clean test tubes (1 to 3), and use the appropriate graduated pipet to add solutions to the test tubes as follows:
tube 1

1. add 3 ml of water and 1 ml of vegetable oil. shake.
2. observe for the initial dispersal of oil, followed by rapid separation into two layers. is vegetable oil soluble in water?______

Explanation:

Step1: Recall solubility concept

Solubility is based on like - dissolves - like principle. Water is a polar molecule and vegetable oil is non - polar.

Step2: Determine solubility

Non - polar substances are not soluble in polar substances. So vegetable oil is not soluble in water.

Answer:

No
