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.
Proteins (S-containing amino acids are cysteine and methionine). Particularly eggs, meat, coffee, vegetables. Sulfur compounds responsible for aroma of onions, leeks, garlic and the compound that makes you cry. Glucosinolates in brassica (broccoli, sprouts, etc.) have potential anticancer properties.

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.
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.
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 substance is...
