Incredible! Why Is Dna Soluble In Water But Not Ethanol
Ethanol CH 3 CH 2 OH and more in general alcohols R-OH have only one. G of ethanol the vapor pressure of the solution at that temperature was 740 102 Torr.

Explain what happened when the ethanol came in contact with the strawberry extract during the DNA extraction.
Why is dna soluble in water but not ethanol. Explain why ethanol is not soluble. When the ethanol and strawberry extract came in contact the DNA was repelled from the ethanol as it does not dissolve in ethanol. Precipitation First Na ions sodium neutralize the negative charges on the DNA molecules which makes them more stable and less water soluble.
The normal boiling point of ethanol is 784C. DNA dissolves in water but not in ethanol. Next alcohol such as ethanol or isopropanol is added and causes the DNA to precipitate out of the aqueous solution because it is not soluble.
When 916 g of a soluble nonelectrolyte was dissolved in 100. A What are the mole fractions. These interactions between DNA and water allow DNA and more in general any hydro-soluble molecule to stay in solution.
