The reason should be determined for expected reasonably the chemistry of dichromate ion which involves mostly in oxidation-reduction reactions and that of chromate ion which involves mostly precipitation reactions. Concept introduction: The term oxidation refers to the loss of electrons by a chemical species and the term reduction refers to the gain of electrons by a chemical species. Oxidation -reduction reactions are those chemical reactions in which both oxidation and reduction take place simultaneously. Precipitation reactions are those chemical reactions in which an insoluble salt is formed due to the reaction between two solutions that contain the soluble salts. Thus, an insoluble salt gets formed which is known as a precipitate.

(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…
