The technique which is not one of the four most common methods for separation and purification is: C. sublimation.
<h3>What is a separation technique?</h3>
A separation technique can be defined as a technique that is typically used to separate, transform, or convert two or more mixture and solution of chemical substances into distinct products such as solutes, chemical compounds or elements.
<h3>The types of separation technique.</h3>
In Chemistry, there are various types of separation technique used for the separation of a solution or mixture and these include the following:
- Filtration
- Evaporation
- Recrystallization
- Extraction
- Fractional distillation
- Decantation
- Simple distillation
- Crystallization
- Sublimation
- Chromatography
Among the aforementioned separation techniques, we can reasonably infer that sublimation is a technique which is not one of the four most common methods for separation and purification.
