Please answer the question in image fastly..It is from redox reactions chapter class 11 chemistry I need to know the method of solving this so please help very urgent..
The equivalent weight is the gram molecular weight divided by the number of electrons lost or gained by each molecule; e.g., potassium permanganate (KMnO4) in acid solution, 158.038/5 g; potassium dichromate (K2Cr2O7), 294.192/6 g; and sodium thiosulfate (Na2S2O3·5H2O), 248.1828/1 g.In case of Sodium Thiosulfate the reation proceeds as under:I2 + 2 Na2S2O3 → Na2S4O6 + 2 NaI2 Na2S2O3 ≡ I2 ≡ Cl2 ≡ 2 eHence Na2S2O3 ≡ 1 eThus Molecular weight devded by 1 is the equivalent weight & hence both have same value
Dear student The ans is wrongly explained, there is no relaton with the question , It is by mistakely published, Actually he was trying to give another ans. Please ignore,Good Luck
In a disproportionation reaction nf is given by:1/nf={1/nf(1)}+{1/nf(2)}So here, nf of s4o6-2 is 2 and nf of s22- is 6Therefore the nf of s2o3-2 is 6/5Dividing the molecular mass of s2o3-2 by nf we get the equivalent mass
