How do you find the equivalent weight of salt?
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 equivalent weight equal to?
equivalent weight, in chemistry, the quantity of a substance that exactly reacts with, or is equal to the combining value of, an arbitrarily fixed quantity of another substance in a particular reaction. The equivalent weight of an element is its gram atomic weight divided by its valence (combining power).
What is the 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.
Is equivalent weight and equivalent mass same?
Equivalent weight (also known as gram equivalent) is 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. Equivalent weight has the dimensions and units of mass, unlike atomic weight, which is dimensionless.
What is equivalent weight of mgso4?
Properties of Magnesium sulfate – MgSO 4

| Melting Point | 1,124 °C |
How do you find the N factor of an equivalent weight?
We need to know that the equivalent weight of the substance is calculated by molecular weightn. This is often inferred that the no. of gram equivalents of a substance is equal to n×number of moles and also Normality =n×molality.
What is the relationship between the equivalent weight and molecular weight?
Equivalent Weight. The weight of a compound that contains ONE EQUIVALENT of a proton (for acid) or ONE EQUIVALENT of an hydroxide (for base). In this example, the magnitude of the equivalent weight of sulfuric acid is HALF of that of the molecular weight.
What is equivalent factor?
Equivalent factors are factors used to convert quantities from their original physical units into a common accounting unit for the purpose of aggregating energy sources or assessing contributions” to environmental problems from diverse sources (for example, the contribution of different pollutants to global warming).
How do you find the equivalent weight of a salt?
Equivalent weight of a salt =molecular wt./total valency of cation.For NaCl eq. Wt.=58.45/1=58.45.ForAlCl3 eq.wt.=133.35/3=44.45.For Al2 (SO4)3eq.wt.=342/6=57. What is the equivalent mass of CaCO3? It is not equivalent mass but equvalent weight. Equivalent weight = molecular weight of compound ÷ charge on compound.
What is the equivalent weight of NaCl in molar mass?
We know that, Equivalent Weight of a Salt = Molar mass of Salt ÷ No. of electrons transferred. In NaCl, 1 electron is transferred from Na to Cl. So, Equivalent Weight of NaCl = (23+35.5) ÷ 1 = 58.5. We also know that, Equivalent Weight of ions = Molecular weight of ion ÷ No. of Electronic charge.
What is the meaning of equivalent weight?
Definition of equivalent weight. : the mass of a substance especially in grams that combines with or is chemically equivalent to eight grams of oxygen or one gram of hydrogen : the atomic or molecular weight divided by the valence. What is gram equivalent and equivalent mass?
What is the molecular weight of the silver carbonate salt?
The molecular weight of the silver carbonate salt is 275.75 g/mol. As we know, Equivalent weight = molecular weight / X The equivalent weight of silver carbonate salt= 275.75 / 2 = 137.87.
