I have no idea. A friend just handed me a glass with some stuff in it and I tried it. I probably only liked it because you don´t notice the alcohol in it as much. Where´s the difference?

Ya it was always neat walking around from like 4-9AM. Could never put my finger on why though. just seemed really, serene watching the city wake up.

Yeah. There´s a castle in our town, lots of old buildings and narrow side streets. I wish I could have taken photos or something. I should probably go out more often just so I can walk home in the morning.

virgin = no alcohol.

I can't even remember the castles today . I wish I did though.

Oh, with alcohol then.

You mean your bad memory, don´t you?

oh nah, I was like 2-4 when I was there, so I don't think I would remember them even with perfect memory.

Ah, you were talking about Germany, lol. I don´t think castles are "typical German" though. If I remember correctly, you mentioned that you lived near Frankfurt (?) because of your dad´s job before. I don´t think there would be any castles for you to remember in this case no matter how old you were, none that I could think of anyway. There are a few ruins in Hesse (which Frankfurt and the place I live are a part of) in general, but don´t think of anything too special though.

My moms dad and his 2nd wife came over to Germany for a little bit to visit and we all(besides my dad) went around to various places. Went to Luxemburg, Austria, and Czech Republic, other areas of Germany for what I'm told "a vacation". So the castles may not have been in Frankfurt.

ok, Neuschwanstein Castle(Bavaria) is the only one I can remember off the top of my head that I can remember being told we visited.

I guess I see how those would be cool memories to have though I personally don´t think Neuschwanstein looks too cool, quite kitschy. Then again that´s only me and I have only seen pictures.

lol, well we have zero culture(I personally wouldn't call it culture) in America, so I would likely be fascinated by a rock in Europe.

Does anyone know what happens if an ester (assuming there are many different ones, but I have no idea at all) and sodium hydroxide solution are put together?

Also, is there a relation between ester(s) and fats? Esters and alcohols? Esters and acids?

Oh wow, I don´t even know if the questions make sense. But that´s about the only thing I could understand (which sadly is not much).

Esters are chemical compounds derived by reacting an oxoacid with a hydroxyl compound such as an alcohol or phenol.

So that's a yes on alcohol.

Esters are usually derived from an inorganic acid or organic acid in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group, and most commonly from carboxylic acids and alcohols. That is, esters are formed by condensing an acid with an alcohol.

So that's a yes on acid to.

ester is basically a result of an alcohol and acid reacting. So there's the relation. It also seems that ester can be broken down into an acid and alcohol.

Most naturally occurring fats and oils are the fatty acid esters of glycerol

yes to fats also. fat is an ester.

by the action of water, dilute acid or dilute alkali

sodium hydroxide is a dilute alkali, so basically sodium hydroxide would be used to create complicated esters? You have to have base to create complex structures. seems that ester requires water, dilute acid, or dilute alkali( the most common). I think, I'm not sure. I'll have to look at it further later, I'm off to play tennis now though. If yo ustill need help later, i'll try to expand on it.

Where´s the difference between (in)organic and carboxylic acids?

fat is an ester.

Is fat made of an acid and an alcohol then? If fat is an ester, is it a specific one and not all esters are fats?

Yes, please.
