(A) if both sentences are true, (B) if both sentences are false, (C) if the first sentence is true but the second is false, and (D) if the first sentence is false but the second is true. 1. In oxygen fixation, the alkaline-iodide-azide solution was used to acidify the solution. The brown hydrated precipitate that formed in the process of oxygen fixation was magnesium hydroxide. 2.Visual inspection is enough to determine if water is of appropriate quality. The standards for drinking water quality are typically set by governments or by international standards. 3.Deeper levels of water often do not reach 100% air saturation equilibrium because they are not shallow enough to be affected by the waves and photosynthesis at the surface. The dissolved oxygen content is an important index when considering its suitability for town supply. 4. The normality (N) of a solution is determined by multiplying the molarity of the solution by its volume. In the standardization of the sodium thiosulfate solution, the factor (f) of KIO3 to be used in computing for its normality (N) is 1. 5.The pH of pure and ideal water is 7. The boiling point of water is influenced by the ambient temperature and the barometric pressure.
