Some solvents are miscible with each other, meaning that they will mix together in a solution. Others are immiscible, meaning that one solvent is unable to dissolve the other. This can occur because of the different polarity of the two solvents or because one solvent has a lower density than the other and sinks below it when mixed. In this blog post we’ll take a look at some examples of immiscible and miscible solvent pairs as well as their physical properties like boiling points, flash points and toxicity so you can make an informed decision about which type to use for your project! Immiscible Solvent Pairs: -Water and Oil -Gasoline and Water Miscible Solvent Pairs: -Oil with Gasoline (a common mixture for cars) -Coffee or Tea with Milk. In this case the coffee/tea is an aqueous solution mixed into milk, which makes it more difficult to separate them out again. The same principle applies to chocolate sauce in ice cream!
