N factor here we mean a conversion factor by which we divide molar mass of substance to get equivalent mass and it depends on nature of substance which varies from one condition to another condition. The reason we had a 5 H2O is because we see that S2O3 has 3 O's but it needs to balance with the 8 O's on the products side. As in the former, the oxidation number change is by 5, in the latter by 6. Using solid thiosulfate: Add 7.0 mg of Product # 46001 (sodium thiosulfate, pentahydrate, ACS grade) for every milligram of chlorine. Equivalent weight (also known as gram equivalent) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance.The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. change in oxidation number= 4x5/2 - 2x2x2, = molar mass / change in oxi. Sodium thiosulfate is an inorganic sodium salt composed of sodium and thiosulfate ions in a 2:1 ratio. Consider the following reaction. Na2s2o3 has the molar mass m. In the reaction na2s2o3 + h2o + cl2 na2so4 + 2hcl + s the equivalent weight of na2s2o3 is - 9732874 Therefore, we add an 5 H2O so each H2O contributes an oxygen to make it 8 oxygens on the reactant side and 8 on the product side.
