I'm using the free version of VMINTEQ 3.1 and I want to simulate titration with NaOH as the titrant, but I could not find OH- on the list. Can anyone teach me how? Thanks!
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.
VMINTEQ 3.1 is a computer program used for geochemical modeling. It allows scientists to calculate the distribution of chemical species in aqueous solutions and predict chemical reactions.
To add OH- species in VMINTEQ 3.1, you can use the "ADD" command or the "DEFINE" command. The "ADD" command allows you to add a single species at a time, while the "DEFINE" command allows you to define multiple species at once.
Yes, you can add multiple OH- species at once using the "DEFINE" command. This command allows you to define the names, charge, and other properties of the species you want to add.
You can specify the concentration of OH- species in VMINTEQ 3.1 using the "EQUILIBRIUM_PHASES" or "SOLUTION" command. The "EQUILIBRIUM_PHASES" command allows you to define the equilibrium conditions, such as pH and pe, while the "SOLUTION" command defines the initial conditions for the solution.
No, there is no limit to the number of OH- species you can add in VMINTEQ 3.1. However, it is important to consider the computational limitations of your computer when adding a large number of species.
