Ternary Interactive Application

Drawing L–L Equilibria

This application is best used on larger screens. It can be used on a mobile phone, although the screen size will impact on the precision of your inputs and navigation around the screen.

Try the question below to see if you can correctly use the ternary equilibria to calculate an equilibrium separation for the system.

The “Hint” button will give you some help in solving the question if you need this.

The “Hit Me” button will start a new question for you.

Q1: Use the data in the tables provided to draw the liquid-liquid 2-phase boundary on the ternary diagram below.
