What are the possible impurities in dmso?
Possible impurities in DMSO (dimethyl sulfoxide) can include water, dimethyl sulfide, dimethyl sulfone, acetone, and other organic compounds. These impurities can affect the stability and purity of DMSO, altering its properties and potential uses. Regular purification methods such as distillation or filtration are typically used to remove impurities from DMSO.
Smell after using dmso?
DMSO can have a garlic-like smell when it reacts with compounds on your skin. This effect is temporary and should dissipate once the DMSO is fully absorbed or evaporated. It's important to use DMSO in a well-ventilated area to minimize the smell.
Is the ozone layer considered a separate layer of the atmosphere?
No it is not. It is there in stratosphere.
What is size of DMSO molecule?
The molecular formula of dimethyl sulfoxide (DMSO) is C2H6OS. The molecular weight of this molecule is approximately 78.13 grams per mole. In terms of size, DMSO has a molecular diameter of about 6.9 angstroms.
What will happen to the mixture of starch and water when it is left overnight?
The starch will settle to the bottom of the container while the water will stay at the top. When left overnight, the mixture may separate further, with a visible layer of water on top and a thicker layer of starch settled at the bottom.
How to mix DMSO with water effectively?
To mix DMSO with water effectively, slowly add the DMSO to the water while stirring continuously. This will help prevent the DMSO from clumping or separating from the water. It is important to mix the two substances thoroughly to ensure a homogeneous solution.
When oil and water are mixed two separate layers form. Each layer is called a what?
Each layer is called a phase. Oil and water separate into different phases due to their differing densities and polarities.
When chlorofrom and water mix which is at the top layer chloroform or water?
Chloroform will be the top layer when mixed with water because it is less dense than water and forms a separate layer due to differences in polarity and solubility.
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?
You can quickly confirm which layer is water and which is chloroform by adding a few drops of water to a test tube containing the layers. Water will mix with the layer that is water, causing it to become more transparent. Chloroform will not mix with water and remain as a separate layer.

What layer floats?
The less dense layer of two immiscible liquids will float on the denser layer.
Is DMSO a protic or aprotic solvent?
DMSO is an aprotic solvent.
Is DMSO a strong nucleophile?
Yes, DMSO is a strong nucleophile.
What can be done to separate oil from water?
Wait. Oil will float on water. Siphon off the top layer after seperation
Why is DMSO used as a control?
Many test compounds (drugs, inhibitors, etc) are not soluble in water and therefore dimethylsulfoxide (DMSO) is used as a solvent instead. The compound dissolved in DMSO is what is used to treat the cell or animal and therefore you must prove that it is the compound, not the DMSO which is causing any results seen. To ensure this, you have a control that contains only DMSO and not the test compound. This is often referred to as a "vehicle control".
How do you separate gasoline and water where gasoline forms the upper layer in the mixture?
Use a separatory funnel to pour the mixture into it and allow it to sit until the layers separate. Open the stopcock to drain off the lower water layer, leaving the gasoline in the upper layer. Repeat the process if necessary for better separation.
What action occurs when oil and water is mixed in a separation funnel?
The oil and water will separate into two layers with oil as the top layer.
