The reaction of sulfuric acid and sodium hypochlorite doesn't stop with the production of sodium sulfate and hypochlorous acid. In water solutions, hypocholorite (HClO) and chlorine (Cl2) reach an equilibrium that is dependent on the pH of the solution. In an acidic solution, the equilibrium ...
Although sulfurous acid does not exist in the free state, it forms stable salts (the neutral sulfite, SO32‑, and the hydrogen sulfite or bisulfite HSO3‑) which are good reducing agents.Sodium sulfite, which is used in pulp and paper bleaching, is usually produced by the reaction of ...
What will happen if MnO_2 was mixed with KBrO_3 and 9 M sulfuric acid? What is the purpose of starch in the experiment: factors affecting reaction rate? If the concentration of HCl is doubled, what effect would it have ...
In addition to aqueous ammonia, bleach and other acids such as sulfuric acid, phosphoric acid, acetic acid, etc. are used for disinfection and pH control. Aqueous ammonia tanks that contain 29 wt. % ammonia are typically present at these operations. A concern is the inadvertent mixing of ...
the researchers first roughed up thesurfacewith hydrogen peroxide and sulfuric acid. This creates negatively charged oxygen groups on the surface to which the N-halamine polymer can attach through a chemical reaction. When the researchers put bacteria on the coated surface, the microbes did not gro...
Process for the preparation of a solid adduct of sulfuric acid and urea A method for processing exposed and developed photographic silver dye- bleach materials, in which the exposed and developed material is treated with aqueous bleaching preparations which contain (a) an acid component, (b) a ...
subjects. Twenty 50 mL beakers were used wherein 25 ml of the saliva and plurality of emulsified carbamide peroxide in the amount to produce viscosities of about 50,000 and 150,000 centipoises were added. The titrating solution was prepared with potassium permanganate in a sulfuric acid ...
have a pH value of below 2 and in particular of below 1. As a rule, the pH is adjusted to this value using strong acids, in particular mineral acids, such as hydrochloric acid, sulfuric acid, nitric acid or phosphoric acid, or also sulfamic acid. Good results are also obtained with ...
Sodium bicarbonate, NaHCO_3, is reacted with concentrated hydrochloric acid at 37.0 degree C and 1.00 atm. NaHCO_3 (aq) + HCl (aq) \rightarrow NaCl (aq) + H_2O (l) + CO_2 (g) The reaction of 6.00 kg of sodium bicarbonate (...
A bleach precursor compound, its peroxygen acid derivative, and detergent compositions containing these materials are disclosed herein. The bleach precursor structurally comprises a quaternized ammoni
