The discussion focuses on using VMINTEQ 3.1 to simulate titration with NaOH, specifically addressing the addition of OH- species. Users discovered that OH- is represented by a negative value of H+ in the software. This clarification resolves the initial confusion regarding the absence of OH- in the species list. The conversation highlights the importance of understanding ion representation in VMINTEQ for accurate simulations.

Ah I figured it out! Apparently OH- is represented by a negative value of the H+. But thanks for the reply!Borek said:I haven't used MINTEQ in ages, but I don't think you can use just OH-, it needs a counterion.
