10 Questions
What is the purpose of decantation?
To separate a liquid from a dense, insoluble solid in a heterogeneous mixture
Which of the following would not be a suitable method for decantation?
Stirring the mixture vigorously before pouring off the liquid
Why would decantation not be a useful method for separating fine silt particles from water?
The silt particles remain suspended in the water and do not form a distinct layer
What is the purpose of using a stirring rod or glass rod during the decantation process?
To prevent the liquid from splashing out of the container
What is the name of the liquid that is poured off during the decantation process?
Supernatant liquid
What is the name of the solid layer that remains at the bottom of the container after decantation?
Sediment
Which of the following is a key requirement for decantation to be an effective separation method?
The solid particles must be insoluble in the liquid
What is the purpose of tilting the container during the decantation process?
To prevent the solid residue from being disturbed when pouring off the liquid
Which of the following is NOT a characteristic of a suitable mixture for decantation?
The solid particles are completely soluble in the liquid
What is the main advantage of using a stirring rod or glass rod during the decantation process?
It minimizes the amount of splashing and reduces the risk of pouring off some of the residues
Learn about the distillation method, a procedure used to separate a mixture of two or more miscible liquids with different boiling points. Discover how distillation is effective for separating a soluble solid from a liquid and how it is similar to evaporation. Explore the distillation setup and the collection of the evaporated substance known as the distillate.
