How do you find the equivalent mass of feso4?
-Equivalent weight of ferrous sulphate = molecular weight of ferrous sulphate/ involved electron. So, equivalent weight of ferrous sulphate which is present as reductant is 151.8 which is equal to the molecular weight of ferrous sulphate.
What is the formula of equivalent mass?
The equivalent masses of acids, bases, and salts are calculated as follows: Equivalent mass of an acid = molecular mass of the acid/basicity. Equivalent mass of a base = molecular mass of the base/acidity. Equivalent mass of a salt = molecular mass of the salt/total positive valency of metal atoms.
How do you find the equivalent weight of fe2o3?
– Molar mass of Fe is given as 59. – Hence, the equivalent weight of iron in ferric oxide, $F{{e}_{2}}{{O}_{3}}$ is 28g/mol. Therefore, the correct answer is (A) 28.
How do you find the N factor of Fe2 SO4 3?
Explanation: Answer. Fe^2+ SO4^2+. HENCE THE N FACTOR IS 2 HERE.
What is the equivalent weight of Fe2?
Iron (atomic weight 55.845) has an equivalent weight of 27.9225 in ferrous compounds (valence 2) and 18.615 in ferric compounds (valence 3). The weight proportion in which elements or radicals combine to form compounds can be determined from their equivalent weights.
What is equivalent formula?
Using the formula: Eq = MW / n. Eq = equivalent weight. MW = atomic or molecular weight in g/mol, from periodic table. n = no. of equivalents.
How do you find the equivalent weight of iron?
Thus, in order to find the equivalent weight of Fe, the atomic mass of Fe is divided by the valency of Fe in the compound.
What is the molar mass of Fe2(SO4)3?
Molar mass of Fe2(SO4)3 = 399.8778 g/mol. This compound is also known as Iron(III) Sulfate.
How do you calculate the n-factor of FeSO4?
To calculate the n-factor, we first find the oxidation states of the elements in both reactant and product side and identify the ones which undergo a change in oxidation state. The oxidation state of Fe changes from +2 to +3. FeSO4 acts as a reducing agent. There is no change in the oxidation state of any element in SO4 (2-).
How many electrons does Fe2O3 lose or gain in SO2?
E.W= M.W of oxidant or reductant/ no of electrons lost or gained. Fe in FeS2 is in +2 state changing to +3 state of Fe2O3. So losing 1 electron. Out of two S atoms one is in — 2 state and another in zero state. But both are changing to +4 state of SO2.
What is the difference between Fe2+ and Fe3+?
Fe2+ will be larger than Fe3+. If we look at an atom, the things that determine size are how many protons are in the nucleus, and how many electrons are in orbitals.
