What is the molecular weight of sodium thiosulphate?
158.11 g/mol
Sodium thiosulfate/Molar mass
How do you calculate equivalent weight from molecular weight?
Equivalent Weight = Molecular weight/ Valency Also, read: Chemical Reaction.
What is the N factor of Na2S2O3?
In the first reaction, one mole of thiosulfate transfers 8 electrons, so the N-factor is 8. In the second reaction, one mole of thiosulfate transfers 1 electron, so the N-factor is 1.
What is the equivalent weight of sodium?
Instead, these chemists had settled on a list of what were universally called “equivalents” (H = 1, O = 8, C = 6, S = 16, Cl = 35.5, Na = 23, Ca = 20, and so on).
How do you find the equivalent weight of sodium thiosulphate?
What is the equivalent weight of sodium thiosulphate? The weight equivalent is the gram molecular weight divided by the number of electrons lost or obtained by each molecule; this is (248.17/1) g for sodium thiosulfate (Na2S2O3. 5H2O).
Why is Na2S2O3 called a hypo solution?
It is used for both film and photographic paper processing; the sodium thiosulfate is known as a photographic fixer, and is often referred to as ‘hypo’, from the original chemical name, hyposulphite of soda.
Which compound has same equivalent weight and molecular weight?
In this example, the magnitude of the equivalent weight of sulfuric acid is the same as the molecular weight. This is beacuse according to the balanced chemical reaction, one mole of sulfuric acid reacts with ONE equivalent of hydroxide.
What is difference between equivalent weight and molecular weight?
The key difference between gram molecular weight and gram equivalent weight is that the term gram molecular weight refers to the mass of a molecule in grams, which is numerically equal to the molecular weight of that substance, whereas the term gram equivalent weight refers to the mass of one equivalent in grams.
What is the molecular formula of sodium?
The chemical formula of sodium nitrate is NaNO3. Its molecular formula is NNaO3 and its molar mass is 84.9947 g/mol. It is the sodium salt of nitric acid (HNO3), and hence, is composed of the sodium cation (Na+) and nitrate anion (NO3-).
What is the molar mass of sodium thiosulfate?
Sodium thiosulfate is an important inorganic salt with several medical uses. It is also called sodium hyposulfite or ‘hypo’.
