What does Phreeqc stand for?

The acronym PHREEQC stands for PH (pH), RE (redox), EQ (equilibrium), C (program written in C).

What is PE in Phreeqc?

pe = 6.999. Activity of water = 1.000. Ionic strength = 2.394e-03. Mass of water (kg) = 1.000e+00.

What is Phreeqc used for?

PHREEQC can be used as a speciation program to calculate saturation indices, the distribution of aqueous species, and the density and specific conductance of a specified solution composition.

What is Visual minteq?

Visual MINTEQ is a freeware chemical equilibrium model for the calculation of metal speciation, solubility equilibria, sorption etc. for natural waters. It combines state-of-the-art descriptions of sorption and complexation reactions with easy-to-use menus and options for importing and exporting data to/from Excel.

What kind of program is PHREEQC version 3?

PHREEQC Version 3 is a computer program written in the C++ programming language that is designed to perform a wide variety of aqueous geochemical calculations. PHREEQC implements several types of aqueous models including two ion-association aqueous models.

What kind of CVODE is used in PHREEQC?

In addition to Runge-Kutta integration, a stiff ordinary differential equation solver (CVODE) has been included for kinetic calculations with multiple rates that occur at widely different time scales.

Which is the USGS version of PHREEQC?

Windows COM 64-bit: IPhreeqcCOM-3.7.0-15749-x64.msi [4M] – COM server, CHM documentation (Both 32-bit and 64-bit COM versions should be installed on 64-bit versions of Windows) This software is a product of the U.S. Geological Survey, which is part of the U.S. Government.

What are the different types of PHREEQC models?

PHREEQC implements several types of aqueous models: two ion-association aqueous models (the Lawrence Livermore National Laboratory model and WATEQ4F), a Pitzer specific-ion-interaction aqueous model, and the SIT (Specific ion Interaction Theory) aqueous model.
