It looks like there may be an extra line before "trona" so that the reader is on the wrong line when it tries to read a chemical equation. Each mineral has one line for the name, followed by one line for the equation, followed by lines containing log_K and delta_H identifiers. It is reading "Trona", the mineral name, when it is expecting the chemical equation. If you still have trouble, I can look at the file.

Parhhurst, I just start working with PHREEQE program (Version 2.0). Firts of all I want to make my own database and I am having some problems that I can not solve so, I have decided to contact you. I am working with cement and concrete materials and I need to introduce in the database compounds like ettringite, CSH gel, etc. For same of the compounds I have not found any problem, but for others I am getting the following message: Ej.: SOLUTION MASTER SPECIES SOLUTION SPECIES PHASES ERROR: equation has not equal sign. ERROR: Trona ERROR: Parsing equation ERROR: Trona ERROR: Equation has no equal sign. ERROR: log_k22.41 ERROR: Parsing equation ERROR: log_k 22.41 EXCHANGE EQUATIONS . . . END I have copy the Trona equations from other database and the same message appears. I know that there is something wrong because when I put calcite in water, portlandite precipitate and I know that this is not a real situation. Please could you help me? Thank you very much in advanced for everything. I am looking forward to hearing from you.
