electrolysis - usually with the addition of a small amount of dilute acid
There are several methods/processes that use electric current to separate a mixture into component parts. Probably the most common is what is called electrophoresis.
It can be electrolysis.
using water for separating
Oil float over the water surface; use a decantation funnel for separation.
Salt water is a solution, a mixture not a "separation".
No, it is only a mechanical separation.
emulsifier. Also, a device that removes oil from water, or water from oil - depending upon its application.
The separation is practically total.
SEPARATION FROM THE WATER
using water for separating
if there is large ratio between aetonitrile and toluene separation can be acheved by using water for layer separation.
Purification
SEPARATION FROM THE WATER
It is more simple to use a separation funnel.
Oil float over the water surface; use a decantation funnel for separation.
a method of separation purify water
Salt water is a solution, a mixture not a "separation".
No, it is only a mechanical separation.
It is called a shadoof.
