8 mar 2020 · The general number of equivalents formula is. E = MW/charge number. Where MW is the molecular weight of the compound and charge number is the number of proton- or hydroxide-equivalents the compound contains. Examples with different acids and bases help illustrate how this works in practice.
30 sty 2023 · Equivalent weight is the ratio of molecular mass and valence factor. It can be calculated by knowing the valence factor for acids and bases, which are the number of replaceable hydrogen and hydroxyl groups, respectively.
The amount of substances that completely react with each other in the reaction is called equivalent weight in chemistry. While answering the question, what is equivalent weight? you should keep in mind that its definition depends on the two factors; the molar mass and valency factor of the compound.
In chemistry, equivalent weight (also known as gram equivalent[1] or equivalent mass) 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.
24 sty 2016 · The formula you were talking about gives the equivalent weight of an element (can be extended to be used with ions). Equivalent weight = (Atomic mass)/(Valency) This could be intuitive and obvious for some.
21 lis 2023 · The Equivalent Weight (EW) formula is: EW = Molar Mass / n number of equivalents. Where "n" number of equivalents is the quantity of charge depending on the substance. If the...
Equivalent Weight. Definitions of Equivalent Weight ( Acid-Base Context ) The weight of a compound that contains ONE EQUIVALENT of a proton (for acid) or ONE EQUIVALENT of an hydroxide (for base). Examples: (1) H 2 SO 4 + 2OH - = 2H 2 O + SO 42-. Molecular weight of sulfuric acid (H 2 SO 4) = 98.07 g/mol.
