Saturation Index vs CO2 addition

[INZILLO]

Hello dear,
I should check how the different saturation indexes vary as a function of the addition of CO2 in the solution.
Are there any examples?
Also can the CO2 be added in moles?

Thank you very much, Dott.dlparkhurst ? you are an invaluable resource.

What I need to do is dissolve CO₂ in a solution, monitor the pH variation, and check for the formation of carbonates.

Based on your previous response:
SOLUTION
pH 7 charge
Ca 1
C(4) 1
END
REACTION 1
CO2 1
0.1 in 2 steps
END
USE solution 1
USE reaction 1
END

Would this be correct?
Is it always a good idea to add equilibrium phases?


Thanks
