Type-III species). Highlight the pH line and hit “F3” which is the “move” key. Choose to move pH to “Type -VI” species. This is necessary, because we don’t want to force the pH to stay at any particular level. In fact, one of the purposes of

pH will not be addressed in this lesson. We will use the default pH value of 7.00 in this example. The Goal To set up a simple chemical equilibrium problem and display its output. Methods Start MINEQL+ by double-clicking on its icon from within the Window
