Question

In the reaction2na2s203+i2 --> na2s4o6+2nai the equivalent weight of na2s2o3 is equal to

Answer 1

Explanation:

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.
