We present evidence that Cl2O and Cl2 can play a greater role than HOCl during chlorination of the herbicide dimethenamid. In this reaction the oxidation state of Cr change+6 to+3 so that the n-factor is 3. 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. Note that the n-factor for acid is not equal to its basicity; i.e. In such a case, we consider the change in oxidation state of atom undergoing oxidation or reduction change per molecule as the n-factor of the species. Sodium thiosulfate, Na2S2O3.5H2O, when reacts with stronger oxidant Cl2 or Br2, it is oxidised to greater extent and gives (SO4)2-, sulfate. This compound is relatively stable and has greater available chlorine than sodium hypochlorite (liquid bleach). Acidity: Number of replaceable OH ion. plz marks as Brainliest Similarly the number of OH ion(s) furnished by the base per molecule is its n-factor, also called acidity. What is the n factor of NaCl 2 See answers deshraj141077gmail deshraj141077gmail Sodium chloride .not sure please check Spriha23 Spriha23 N = 1 because in case of ionic solid (NaCl) the n factor is equl to charge on cation. Sodium hydroxide reacts with chlorine gas in different ways according to the concentration and temperature of the solution and it gives different products. But, one thiosulfate ion has two sulphur atoms, hence, n-factor i.e., total change in oxidation number per molecule is 0.5 x 2 = 1. If 50 g of each of the following metals absorb the same amount of heat which metal will show the greatest temperature increase. In Neutral medium,K2Cr2o7+H2o=2KCrO4^-2 +2H^+.
