What is supernatant short answer?
The supernatant is the clear liquid that lies above the solid residue after centrifugation, precipitation, crystallization or settling. The liquid is normally free of precipitate and has a lower density. Supernatant is also known as supernate.
What is difference between supernatant and precipitate?
As nouns the difference between precipitate and supernatant is that precipitate is a product resulting from a process, event, or course of action while supernatant is the liquid that lies above a sediment or precipitate; supernate.
What are cell-free supernatants?
Cell-free supernatant generally refers to the method where algal cells are removed by centrifugation and the supernatant is used for NP biosynthesis.
Why is supernatant important?
The supernatant is used in various industries and helps in analyzing the properties of several materials and components. It is widely used in the corrosion and bio-corrosion industry either for analyzing or making the corrosion inhibitors.
What is supernatant in chemistry?

What is a supernatant made of?
The supernatant is composed of the lighter particles which make it to float over the denser sediment or precipitate. The supernatant can then be analyzed further or processed for other uses as happens in the preparation of corrosion inhibitors.
What is the difference between liquid and supernatant?
The liquid is normally free of precipitate and has a lower density. The process leading to the supernatant formation is used in separating the several components making up a complex mixture.
