If these compounds are shaken in a test tube for 10-20 sec will they form a miscible (1 layer) or immisible (form 2 layers)?
a) water and ethyl alcohol
b)water and dimethyl ether
c)water and methylene chloride
d)water and hexane
e)Hexane and methylene chloride
Am I correct? I'm trying to predict what will happen before I do this in lab.
All of these look ok. My Merck Index lists ether as slightly soluble in water and water slightly soluble in ether. Sol ether in water is 8.3%(w/w). From that I would think miscible. It has been so long since I did this in the lab I've forgotten.
My lab book recommended that the Merck Index be used to look stuff up about the individual chemicals but it's quite costly, however it is simpler to look in 1 book rather than surfing the internet for awhile and having to site all the sources of the chemical information.
Most libraries have it.I bought mine from Amazon.com and bought a used copy for about half price. It's about 10 years old now and was about 2-3 years old when I bought it. So-called out of date copies are always a good bargain.
Hm..I'll look for one then.
Thanks Dr.Bob =)
I forgot to say Thank You Dr.Bob =D
