SUMMARY
The discussion confirms that total alkalinity and total carbonate concentration can be used to determine the pH of a solution. The formula for total alkalinity is given as Total alkalinity = [OH]- + [HCO3]- + 2 x [CO3]2- - [H]+. Participants emphasize the importance of considering other ions present in real water, which can affect alkalinity. Additionally, the impact of carbon dioxide saturation on alkalinity is highlighted as a significant factor in pH determination.
