What else can I help you with?
Is DCM lighter than water?
No. Dichloromethane is far denser than water will be the bottom of the two layers when the two are mixed.
When dichloromethane is mixed with water will the organic phase be in the upper level or lower level?
The organic phase, which contains dichloromethane, will be in the lower level when mixed with water. Dichloromethane is denser than water, so it will settle to the bottom layer due to its higher density.
Is dichloromethane miscible in water?
Yes, dichloromethane is miscible in water, meaning it can mix and dissolve in water.
What is the solubility of dichloromethane in water?
Dichloromethane is not very soluble in water, with a solubility of about 1.3 grams per 100 milliliters of water at room temperature.
Why did the caffeine leave the water and move into the dichloromethane?
Caffeine is more soluble in dichloromethane than in water due to differences in their polarity. When caffeine is added to the water-dichloromethane mixture, it is preferentially dissolved in dichloromethane, which is a non-polar solvent. This movement is driven by the principle "like dissolves like", where compounds tend to dissolve in solvents with similar polarity.

What color is iodine when mixed with dichloromethane?
When iodine is mixed with dichloromethane, the resulting color is purple or violet.
Is dichloromethane miscible in water?
Yes, dichloromethane is miscible in water, meaning it can mix and dissolve in water.
Which of the two layers that are formed during the extraction is dichloromethane?
Dichloromethane typically forms the organic layer during an extraction process, as it is immiscible with water and has a higher density. After shaking the two layers and allowing them to separate, the bottom layer (organic layer) is usually the one containing dichloromethane.
What is the solubility of dichloromethane in water?
Dichloromethane is not very soluble in water, with a solubility of about 1.3 grams per 100 milliliters of water at room temperature.

What substance turns dichloromethane to a violet color?
Bromine water turns dichloromethane to a violet color.
Which of these solutes settle at the bottom when mixed with water?
Sand and sugar are examples of solutes that will settle at the bottom when mixed with water due to their higher density compared to water.
Does dichloromethane layer lie in water layer?
No, dichloromethane is less dense than water and will form a separate layer on top of water due to their immiscibility. This allows for the easy separation of the two layers in a liquid-liquid extraction process.
Would gasoline turpentine or mercury settle to the bottom when mixed with water?
Gasoline and turpentine are less dense than water and would float on the surface, while mercury is denser than water and would sink to the bottom when mixed with water.
How does adding anhydrous sodium sulfate to the dichloromethane solution remove water?
Anhydrous sodium sulfate is a desiccant, meaning it has a strong affinity for water. When added to a dichloromethane solution, the anhydrous sodium sulfate will absorb any water present, effectively removing it from the solution by forming a hydrated salt. The water-free dichloromethane can then be decanted or filtered off for further use.
