neutral. Anything from pH 7 to pH 0 is considered ,acidic, and from 7 to 14 pH is alkaline. The more ,acidic, the solution, the more H 3 O+ (hydronium) ions are present, and the less OH-(hydroxide) ions present. This relationship is always constant, and so knowing one, we can determine the other. Equation 7 …

16/5/2020, · SO 2 which is acidic in nature and possesses high solubility in water, may easily react with hydroxyl ions on the moist basic surface of the sorbents (Rosas et al. 2017). Depending on the type of sorbents used, the presence of water in wet FGD may or may not have a significant effect on the SO 2 removal efficiency.
