Does salt dissolve into ethanol

Answer 1

It should be able to, when the salt is previously dissolved in a little bit of water. See, methanol is made up of one CH3 group and an OH group. The -OH group is polar (meaning it should mix with WATER). The CH3 group is NOT polar (will not mix).

As you go up the list of alcohol, you'll see that the CH chain grows (for example Ethanol is C2H5OH). The more CH chains there are, the more NONPOLAR the compound gets, meaning the less it can dissolve water! This is also why Octanol (Gas fuel, I believe, which contains 8 CH chains) doesn't dissolve anything that is considered polar!

Conclusion: Methanol sounds like the best to dissolve a salt in (that is dissolved in water), because of its polar vs. Nonpolar ratio (compared to similar alcohols). However, don't quote everything I say on here. Some of it is based on theory, and I haven't quite experimented with it.

Answer 2

Salt (Sodium Chloride) is fully soluble in water but is slightly soluble in ethanol. The structure of ethanol is slightly non-polar at one end and polar at the other. the polar group is the (-OH) group. The (-OH) group helps ethanol's property as a solvent for polar substances such as salts. The (-OH) group does this by using the negatively charged oxygen ion (of the (-OH)) to attract some of the positively charged sodium ions and using the positively charge hydrogen to attract some of the negatively charge chlorine ions. Because not all of the sodium chloride molecules are pulled apart, not all of the sodium chloride molecule dissolve. This is why sodium chloride is considered to slightly soluble in ethanol.

Answer 3

I wouldn't be so sure. There is a difference between Methane and Water; that methane doesn't have this dissolving property. For example, if you put some crackers in water, they'll become soggy and soon deteriorate. If you put them in liquid methane, however, when you take them out they'll be just as crisp as if they were dry. So to answer your question, salt in liquid methane may very well stay in crystal form. I think the only way to know for sure is to try it out!

Answer 4

This is highly unlikely. Salts dissolve in water due to its polarity. Liquid methane would be a non-polar organic solvent, so salts would not readily dissolve.

Answer 5

Yes, salt can dissolve in ethanol. However, salt's solubility in ethanol is lower compared to its solubility in water.

Answer 6

No it can not
