Saturated and Unsaturated Vapour Pressure

Saturated and Unsaturated Vapour Pressure What is a saturated solution? If in a water sugar solution, the amount of dissolved sugar is equal to the maximum amount that a given amount of water can dissolve at a certain temperature, then that solution is called a saturated solution. What is an unsaturated solution? If in a water sugar solution, the amount of dissolved sugar is less than that amount that a given amount of water can dissolve at a certain temperature, then that solution is called a saturated solution. What is saturated vapour? At a certain temperature in an enclosed space, if the amount of vapour present is equal to the maximum vapour capacity of that space, then that vapour is called saturated vapour. What is unsaturated vapour? At a certain temperature in an enclosed space, if the amount of vapour present is less than the maximum vapour capacity of that space, then that vapour is called unsaturated vapour. What is vapour pressure? Vapour enclosed in a container behaves

Separating liquid/liquid mixtures

 Separating liquid/liquid mixtures

In recent years there have been many oil tanker disasters, just like the one shown in Figure. These have resulted in millions of litres of oil being washed into the sea. Oil and water do not mix easily. They are said to be immiscible. When cleaning up disasters of this type, a range of chemicals can be added to the oil to make it more soluble. This results in oil and water mixing with each other. They are now said to be miscible. The following techniques can be used to separate mixtures of liquids.
