I had a query with regards to alkaline (pH 10) solutions and CO2. I have a solution whose composition is listed below and I am bubbling CO2 through the solution. I want to see how long at a given flow rate (x litres of CO2) before I have the precipitation of a certain amount of CaCO3. I can't seem to get the output right no matter what I try. I need to keep the pH constant for the entire reaction. Is the following code correct for what I am doing?
SOLUTION 1 Nutrient Solution, pH 10, No CO2
Cl 256 charge
-water 1 # kg
GAS_PHASE 1 CO2 addition
Also when I increase the pH, it returns lots of errors. Any help you can give would be great.
