How do you find the equivalent weight of Mohr salt?
How do you find the equivalent weight of Mohr salt?
Therefore, n-factor of Mohr’s salt = change in oxidation state of Fe. Thus, n-factor = 1. The equivalent weight is molecular weight divided by the n-factor. Thus, we get the equivalent weight = Molecular weight.
What is equivalent weight of Mohr salt?
1
Equivalent weight of mohr�s salt is 1.
What is equivalent weight of Mohr’s salt undergoing oxidation in acidic medium?
392 g/mol
in acidic medium is 392 g/mol. Note: Equivalent weight is also known as gram equivalent). It is defined as, “the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance”.
How do you find the equivalent weight of a salt?
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.
What is the equivalent weight of Na2CO3?
106 g/mole
Answer: 53 g/eq The salt Na2CO3 ionizes to produce 2Na+ and CO3-2. So the charge on both ions is 2. Therefore, the molar mass of Na2CO3 is 106 g/mole.
What is the formula of Mohr salt?
(NH₄)₂Fe(SO₄)₂·6H₂O
Ammonium iron(II) sulfate/Formula
What is the equivalent weight 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 equivalent mass of kmno4?
potassium permanganate has a molar mass of 158.034(1) g mol−1, and reacts with five moles of electrons per mole of potassium permanganate, so its equivalent weight is 158.034(1) g mol−1/5 eq mol−1 = 31.6068(3) g eq−1.
What is equivalent weight na2co3?
Equivalent weight of Na2CO3 = 106 / 2 = 53 g/eq.
What is equivalent weight of KMnO4?
What is the equivalent weight of Na2SO4?
Question: The equivalent weight of Na2SO4 are? (Theanswer is 71 g/Equiv) Could you please explain this problem indetail I have hard time with understanding the valence rules andwhat to divide, thanks.
What is the equivalent weight of cacl2?
Answer:Therefore 55 grams of calcium chloride is the equivalent weigh because 55 grams of calcium chloride would supply one mole of positive or negative charges when dissolved in water.
How to calculate the molar mass of Mohrs salt?
The molar mass of mohr’s salt = 392 g/mol Strength = Normality x Equivalent weight = (1/20) x 392 = 19.6 g/L For preparing 250ml of N/20 Mohr’s salt solution, Mohr salt required
Why are the solutions of Mohr’s salt acidic?
It is important to note that the solutions of Mohr’s salt are usually slightly acidic, which can be explained by the presence of ammonium cations in them. It can also be noted that sulfuric acid can be added to solutions of Mohr’s salt in order to prevent the oxidation of the ferrous ion to the ferric ion.
Which is the normality of Mohrs salt and KMNO 4?
N 1, N 2 are normality of Mohr’s salt and KMnO 4 solution respectively. V 1, V 2 are volume of Mohr’s salt and KMnO 4 respectively. The strength of and molarity of given KMnO 4 solution is found out as 2/y x 31.6 g/l and N/5 moles/liter, respectively.
Where does the name Mohr’s salt come from?
It can be noted that Mohr’s salt is named after the German scientist Karl Friedrich Mohr. When dissolved in water, Mohr’s salt (like most other salts of ferrous sulfate) dissolves to yield an aquo complex with the chemical formula [Fe (H 2 O) 6] 2+.
