Water and chloroform are mixedthe components separate into two layerseach of which smells strongly of chloroformHow would you quickly and easily confirm which layer is water and which is chloroform?
Always the bottom layer will be of chloroform and upper layer of water due to difference in the density.
Why chloroform is immiscible with water?
Chloroform (CHCl3), although it is polar, cannot form hydrogen bonds with water and thus the interactions between chloroform and water are too weak to be miscible. In addition, chloroform is significantly heavier than water and will form a bottom layer if mixed.
When chlorofrom and water mix which is at the top layer chloroform or water?
water
Is chloroform soluble in water?
No they are not. Water will float on chloroform as the latter is more denser than the former.
What happened inside a beaker and on the bottom of the glass cover after you heated the water in the beaker?
Water can be condensed on the bottom of the glass cover.
Explain briefly how you would separate chloroform or dichloromethane extract from an aqueous solution using a separating funnel?
Both chloroform and dichloroform are denser than water. You will see two layer in separating funnel. The lower layer will be chloroform and upper layer would be aqueous layer.
Can a seed put in a beaker of water with a layer of oil germinate?
no
How do you separate sand from soil?
Take 100 ml beaker put you material which has sand and dirt in it and stir with a stirring rod 10- 15 minutes. Once you are done with that you then allow the beaker to stand for 20-30 minutes gradually as time goes you will see the different layer in the beaker with sand at the bottom of beaker as it is heavier than dirt and then a layer of dirt on it.
How do i Separate naphthalene potassium chloride and sand?
Add warm water to dissolve the KBr which is very soluble. This would become the aqueous layer and would be more dense and thus at the bottom. Add them to a sep funnel and decant. Evaporate the water off and you have the KBr. The remaining fluid in the sep funnel is npahthalene
Kate and Janie are about to pour water into a beaker when they notice the beaker has a crack at the bottom. What should the students do with the beaker?
Inform their teacher and then throw the beaker in the broken glass
What will happen to dye crystals initially in the bottom of a beaker of water over a long period of time?
They will diffuse equally throughout the beaker
What happens with water and chloroform and soap solution combined?
Water is a polar solvent while chloroform is a non-polar solvent. There is a popular aphorism used for predicting solubility which is "like dissolves like". Water and chloroform have different solubility. Therefore, chloroform is insoluble in water and will just form a layer when mixed. But in the presence of soap solution, they can mix together. Soap serves as an emulsifying agent that will reduce the surface tension of the solution.
