Hi, I was wondering if you could help us out. We want to do a pretty simple calculation with phreeqc. We have a set of solution data and want to know what phases will deposit from that solution. We don not however, have a measured pH and want the programme to calculate this for us. If we do not specify the pH, it is calculated as 7.0. We know that the pH will be quite high in these solutions so a pH of 7.0 is not realistic, especially as some of our phases are very pH dependant. We have read in a paper that the pH can be calculated by charge balancing the species in solution with ?OH? Can you let us know if this is possible with phreeqc or if there is some other way of calculating an unknown pH. Kind Regards Nic & Camelia.
