WebApr 19, 2024 · Excess Chlorine is destroyed by its reaction with Sodium Thiosulfate (Na2S2O3) according to the unbalanced equation Na2S2O3 + Cl2 + H2O → NaHSO4 + HCl. * How many moles of Na2S2O3 are needed to react with 0.40 moles of Cl2? A. 0.10 mol Na2S2O3 B. 0.20 mol Na2S2O3 C. 0.30 mol Na2S2O3 D. 0.40 mol Na2S2O3 E. 0.50 mol … WebDivide the component's molar mass by the entire molecular mass. You will now have a number between 0 and 1. Multiply it by 100 to get percent composition! Tips for solving: The compounds will always add up to 100%, so in a binary compound, you can find the % of the first element, then do 100%- (% first element) to get (% second element)

WebTo prepare 1000 mL of a 0.1 mol/L solution of Sodium thiosulfate we have to dissolve 24.8186 g of Na2S2O3×5H2O (100 % purity) in deionized or distilled water. After the solid is completely dissolved, dilute the solution to a final volume with deionized (distilled) water. Transfer the prepared solution to a clean, dry storage bottle and label it. WebNa2S2O3. Oxidation state of 'S' you do not know, ok. Oxidation state for sodium = 1, So, Two sodium gets (1+1)= 2. Your question is oxidation state for sulphur, So unknown, There are two sulphur ... Upon heating to 300 °C, it decomposes to sodium sulfate and sodium polysulfide: 4 Na2S2O3 → 3 Na2SO4 + Na2S5 Thiosulfate salts characteristically decompose upon treatment with acids. Initial protonation occurs at sulfur. When the protonation is conducted in diethyl ether at −78 °C, H2S2O3 (thiosulfuric acid) … See more Sodium thiosulfate (sodium thiosulphate) is an inorganic compound with the formula Na2S2O3·xH2O. Typically it is available as the white or colorless pentahydrate, Na2S2O3·5H2O. The solid is an efflorescent (loses … See more Sodium thiosulfate is used predominantly in industry. For example, it is used to convert dyes to their soluble colorless forms, which are called leuco. It is also used to bleach "wool, cotton, silk, ...soaps, glues, clay, sand, bauxite, and... edible oils, edible fats, and … See more On an industrial scale, sodium thiosulfate is produced chiefly from liquid waste products of sodium sulfide or sulfur dye manufacture. See more Two polymorphs are known as pentahydrate. The anhydrous salt exists in several polymorphs. In the solid state, the thiosulfate anion is tetrahedral in shape and is notionally derived by replacing one of the oxygen atoms by a sulfur atom in a sulfate anion. … See more chef jacket embroidery
