Extraction of a acid/base
« on: November 15, 2012, 06:25:29 AM »
Hey

Ive been given a task to separate an unknown amount of HCl, NaOH and diethyl ether which
together make up 1 g in a liquid mix.
so the task is to get the amount of each of these substances.
I've read much about acid/base extraction but that involves organic compounds in either acid
or base form and extraction is made by HCl for the base and NaOH for the acid which gives
ionic forms of the compounds which then can be separated by a funnel.

But I'm little shorthanded on information on how to separate these since HCl and NaOH make
water + NaCl when they mix which will form a two layer since diethyl ether is immiscible in water
in a funnel. But how can u separate the HCl and NaOH to get their separate value?

any help on procedure for this task is greatly appreciated

You already know how to amount of diethyl ether.
How do you think one can determine the amount of NaOH and HCl that was present?
Hint : measure the pH of the aqueous layer and as you said the combination of these two gives NaCl.
