Does Alcohol React with Acid to Produce Salt or Ester?

AI Thread Summary
The discussion centers on the interaction between alcohols and acids, specifically regarding the formation of salts or esters. It highlights that while ethanol can form esters with inorganic acids, the outcome depends on the specific alcohol and acid involved. The conversation also touches on sodium stearate (C17H35CO2Na), clarifying that it is a salt. When treated with an acid, sodium stearate can yield stearic acid. If excess acid is present, the reaction can lead to the formation of a stearate ester and water. The process may reverse if water accumulates, indicating the dynamic nature of these chemical reactions.

I am uncertain if alcohol react with acid ( not carboxylic acid ) will produce salt or ester.

Well I know that ethanol will form esters with inorganic acids, but I wouldn't make a generalization based on this. I would say that it depends on the alcohol and what type of acid you're dealing with.
 
Hi pzona! thanks for your reply.
How about C17H35CO2NA ?
 
Well I could probably look it up and give you an answer, but I haven't taken a college level organic chem course yet (just an overview class in high school), so I don't feel like I would be able to fully explain it in detail. I'll leave this to someone else who is a little more experienced.
 
Thanks anyway (= your help is greatly appreciated

What is the actual structure here, this could be many different things, to be completely honest - do you have a name?
 
Besides, this looks like salt, not an acid itself.

This is sodium stearate. In the presence of an acid the salt produces the carboxylic acid known as stearic acid. If you were to treat the sodium salt of the stearic acid (sodium stearate - a soap) with both alcohol and an inorganic acid, like HCl or H3PO4, you would first produce stearic acid. This would use an equivalent of acid. If you have more than an equivalent of acid present (and it only need be present in catalytic amounts) you would begin to produce a stearate ester and a molecule of water. This reaction would continue until the alcohol or the stearic acid were used up or if the water began to build up in sufficient amounts to reverse the reaction back to the starting materials.
