Webb16 feb. 2024 · pH Scale. Acidity is commonly measured using the pH scale. Pure water has a pH of about 7, which is considered neutral. A substance with a pH less than 7 is considered to be acidic, while a substance with a pH greater than 7 is considered to be basic or alkaline. The lower the pH, the more acidic the substance. WebbTotal Alkalinity and pH reduction. Since CO 2 determines the pH of the water, let's think about this another way. If you want to reduce pH, you need more dissolved CO 2 (carbonic acid). You can either inject CO 2 directly to lower pH, or you can use acid. But wait, acid doesn't contain CO 2...so where does acid find CO 2?. Acid converts alkalinity into …
