Question

Equivalence factor of sodium thiosulfate and iodine

Answer 1

Answer:

The equivalent weight is the gram molecular weight divided by the number of electrons lost or gained by each molecule; For sodium thiosulfate (Na2S2O3. 5H2O), this is (248.17/1) g. Thus Molecular weight divided by 1 is the equivalent weight & hence both have same value.

35.5 grams of chlorine are equivalent to 127 grams of iodine; 35.5 and 127 are the equivalent weights of chlorine and iodine respectively. Hydrogen also has an equivalent weight equal to its atomic weight
