Chemistry

Slav-nsk [51]3 years ago
7 0

Sand and water can be separated by any of the following methods:

1. Sedimentation and decantation: This method involves the mixture being kept undisturbed for some time. After some time, sand being heavier and insoluble in water, settles down at the bottom of container. Now, water is poured into another container to separate it from sand.

2. Filtration: This method involves the mixture being passed through a filter paper (a filter with very fine pores). Sand particles being larger in size are retained by the filter paper and get separated from water.

I hope this helps! :D

Darina [25.2K]

Answer:

a) The functional group that will be evident in the IR spectrum is the OH group.

b) OH group appears between 3200-3600 cm⁻¹

c) An important impurity that have the same functional group is water.

Explanation:

Eugenol is a chemical substance that consist in a benzene that have in 1 an alcohol, in position 2 a methyl ether and in position 4 an 1-propene bonded by the terminal alkyl carbon.

a) Having this in mind, the functional group that will be evident in the IR spectrum is the OH group.

b) This OH group appears between 3200-3600 cm⁻¹

c) An important impurity that have the same functional group is water. When you have water in your sample a big signal will appear in this zone and it is possible that overlapes the OH signal of eugenol.

I hope it helps!
