How do you find the equivalent weight of a redox reaction?
Equivalent weight of a substance (oxidant or reductant) is equal to molecular weight divided by number of electrons lost or gained by one molecule of the substance in a redox reaction.
How do you find the equivalent weight of a molecule?
Equivalent Weight = Molecular weight/ Valency Also, read: Chemical Reaction.
How do you find the equivalent weight of an oxidizing agent?
Equivalent weight of a substance (oxidant or reductant) is equal to the molecular weight divided by the number of electrons lost or gained by one molecule of the substance in redox reaction. So, our answer is 31.6 per equivalent.
How do you calculate equivalent reactions?
To calculate molar equivalents for each reagent, divide the moles of that reagent by the moles of the limiting reagent: Note that the molar equivalency of sodium benzoate is 1. This is because sodium benzoate is the limiting reagent. Any reagents used in excess will have a molar equivalency greater than one.
How do you find equivalent weight?
The equivalent weight of an element is its gram atomic weight divided by its valence (combining power).
How do you calculate equivalent?
To calculate the equivalent mass of a base, simply divide the molar mass of the base by the number of hydroxyl groups. Take, for example, calcium hydroxide Ca(OH)₂. A few simple calculations yield an equivalent of 37g/mol. To find the equivalent of an acid, divide the acid’s molar mass by the number of protons.
What is intramolecular redox?
Intramolecular redox reactions are the reactions in which a single compound undergoes reduction-oxidation by the process of decomposition.
How do you compare oxidizing agents?
Oxidation is the removal of electrons from an atom or polyatomic ion. The higher the electronegativity the greater the pull an oxidizing agent has for electrons. The higher the pull for electrons the stronger the oxidizing agent. So the element with the highest electronegativity is the strongest oxidizing agent.

How do you find the equivalent weight of an element?
Equivalent weight = Molar mass / Valence factor. (The Valence factor for a base = acidity of the base, the Valence factor for an acid = basicity of the acid and the Valence factor for an element = valency)
What is equivalent weight (GWe)?
Equivalent weight is a relative quantity so it does not have any unit. When we express the equivalent weight of a substance in grams, we call it Gram Equivalent Weight (GWE). How to Calculate Equivalent Weight? Equivalent weight = Molar mass / Valence factor
What is the equivalent weight of calcium hydroxide base in grams?
The molecular weight of the aluminium hydroxide base is 78 g/mol. As we know, Equivalent weight = molecular weight / X The equivalent weight of calcium hydroxide base= 78 / 3 = 26. Equivalent Weight of the Metal in Salt or Compounds
How do you find the equivalent mass for disproportionation reactions?
For disproportionation reactions, use a trick to find equivalent mass; E = E1 + E2; where E1 and E2 are equivalent masses of oxidation and reduction half reactions of same element. Now, find the n-factor (total change in oxidation number per molecule) and then equivalent mass = molar mass/n-factor.
