Is acetic acid soluble in hexane?
Yes, but only slightly soluble.
Is hexane acidic or alkaline?
Neither. Acidic and alkaline are terms that refer to pH, and pH is only used for aqueous solution. Hexane is NOT soluble in water, and as such, pH is not relevant.
What is the pka of cyclohexane?
pKa is measured for acid in aqueous solution while hexane is an organic liquid immiscible with water so pKa value is meaning less for hexane.
The purpose of adding hexane to the aqueous solutions of halogens?
to indicate the changes of colour and to determine whether displacement of halogen occur
What are examples of Organic molecules of proteins?
Phibosourclicilin Chyctosenaupces Suorcrisiliosics
Is acetic acid soluble in hexane?
Yes, but only slightly soluble.
In what coumpounds in hexane most likely to dissolve nonane ethyl alcohol ammonium hydroxide water or acetic acid?
nonane and hexane are miscible as both are non polar
How do you store potassium safely?
Potassium is stored in not aqueous or non-protic solvents such as kerosene or hexane
Is hexane acidic or alkaline?
Neither. Acidic and alkaline are terms that refer to pH, and pH is only used for aqueous solution. Hexane is NOT soluble in water, and as such, pH is not relevant.

What is a good alternative to hexane?
Super critical carbon dioxide is my favorite but one can use ethanol propane and enzymatic aqueous extractions as well as mechanical press extraction.
Can you use ethanol in extraction with water?
No, ethanol and water are miscible. For an extraction, you want two solvents that are immiscible (mutually insoluble). Standard choices for the organic phase are ethyl acetate or dichloromethane. For the aqueous phase, use water, aqueous acid or aqueous base, depending on the compound you are trying to isolate.
Why is hexane an appropriate solvent for extracting fat from hamburger meat?
Hexane is a non-polar solvent. Fats are also non-polar substances. Fats are thus highly and rapidly soluble in hexane as compared to any other solvent. Therefore, if a total fat content determination is required, hexane is the best while not suitable for polar and partially polar lipids. For determination of total lipids including all polar, partially polar and non-polar fats, the best described system is Chlroform:Methanol (3:1).
What is difference between hexane and n-hexane?
Hexane is a hydrocarbon with the chemical formula C6H14. n-hexane is the unbranched isomer of hexane as there exists four more branched isomers of hexane
In which is KNO3 soluble benzene hexane or water?
Potassium nitrate is soluble in water, as it is an ionic solid. When dissolved in water, potassium nitrate will form an aqueous solution of potassium and nitrate ions.
Is hexane is a compound?
Hexane is a compound.
