Question

true or false
2. Sedimentation is carried out after decantation.
3. A mixture of sugar and water is separated through
filtration​

Answer 1

2.False , because decantation is the process in which the clear liquid is poured into another beaker after the solid particles settle down i.e sedimentation. Thus decantation occurs after sedimentation.
3. False because sugar is completely dissolved in water so no residue will remain after passing through the filter paper. But we can separate this solution by evaporation ; but in that case water will not be obtained by sugar will be left out and separated.

Answer 2

Answer:

2. True

3. False

Explanation:

2. True. When the heavier component in a mixture, particularly solids, settles after water is added to it, the process is called Sedimentation. If a mixture of such liquids is allowed to stand for some time, they form two separate layers. The component that forms the top layer can then be separated by Decantation.

3. False. When sugar is mixed with water it creates a homogeneous solution, meaning you can't see the individual particles, unlike when you mix sand with water. The sugar water is a solution because no chemical reaction occurs, but to separate it you need to create a chemical reaction by distilling the liquid.
