(Kb= 5.6 x 10-10) Calculate the pH of a 0.15 M solution of sodium acetate (CH3COONa). What is the percent hydrolysis? (Kb= 5.6 x 10-10) Problem 164AE: Calculate the pH of a 0.010-M solution of iodic acid (HIO3, Ka = 0.17). Sodium sulfite (sodium sulphite) is the inorganic compound with the chemical formula Na2SO3. A white, water-soluble solid, it is used commercially as an antioxidant and preservative. A heptahydrate is also known but it is less useful because of its greater susceptibility toward oxidation by air. See more Sodium sulfite can be prepared by treating a solution of sodium hydroxide with sulfur dioxide. When conducted in warm water, Na2SO3 initially precipitates as a white solid. With more SO2, the solid dissolves to give the See more Sodium sulfite is primarily used in the pulp and paper industry. It has been also applied in the thermomechanical conversion of wood to fibres (defibration) for producing medium density fibreboards (MDF). As an oxygen … See more According to X-ray crystallography sodium sulfite heptahydrate features pyramidal SO3 centers. The S-O distances are 1.50 and the O-S-O … See more Sodium sulfite is primarily used as a mild reducing agent. The heptahydrate crystals effloresce in warm dry air. Heptahydrate crystals also oxidize in air to form sodium sulfate. The anhydrous form is more resistant to oxidation by air. Sodium bisulfite, … See more
