For example, Equivalent weight of acid = molecular weight of acid/basicity of acid The acid H2SO4 can donate 2 hydrogens. 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. 1 + Wt. • When calculating Leak Off Test Equivalent Mud Weight, ROUND DOWN to one decimal place (for example: round down 11.76 ppg to 11.7 ppg; round down 13.89 ppg to 13.8 ppg). Equivalent weight depends on type of the substance. Print Equivalent Weight: Definition & Formula Worksheet 1. equivalent weight: The equivalent weight of an element or radical is equal to its atomic weight or formula weight divided by the valence it assumes in compounds. Name Formula Molecular Weight Equivalent Weight Aluminum Sulfate Al 2(SO 4) 3 18H 2O 666. of Mixture = Total Weight of Mixture Wt. The formula to calculate the equivalent weight is given as: Equivalent Weight = Molecular weight/ Valency. Theoretical Equivalent weight of sulfuric acid (H 2 SO 4) = 49.03 g/equivalent of H + Reasoning: Thanks. Calculating equivalent mass Defining the equivalent of a substance. of the mixture to determine proper stoichiometric ratios with the curing agent. 2 Example 1: A mixture of 80% Liquid Epoxy Resin (E.E.W. What is the correct setup to determine the equivalent weight (EW) of fluorine? A metal oxide contains $60$% metal.The equivalent weight of metal is (1) $12$ (2) $60$ (3) $40$ (4) $24$ I know that the equivalent weight of metal oxide = equivalent weight of metal + 8.But how can i arrive at the answer with this. Equivalent weight of Oxidising and Reducing Agents. Any help appreciated. 1 E.E.W. Examples: (1) H 2 SO 4 + 2OH-= 2H 2 O + SO 4 2-Molecular weight of sulfuric acid (H 2 SO 4) = 98.07 g/mol . 2 E.E.W. Share Tweet Send [Deposit Photos] The equivalent of a substance, also known as the equivalent quantity of a substance, refers to the quantity of a substance that interacts with one mole … The equivalent weight of an element or radical is equal to the ratio of it's atomic weight or formula weight devided by it's valency. g eq−1kg eq−1. For example, consider the reaction, H 3 PO 4 → HPO 4 2-+ 2H + The molecular weight of a chemical reaction is 98, and the valency is 2, then the equivalent weight of H 3 PO 4 is. Fluorine is the ion (F-1) and its molar mass is 19 g. This is accomplished with the following equation: Equation 1: E.E.W. It is essential to determine the Epoxy Equivalent Weight (E.E.W.) Learn more about Appendix 2: Molecular and Equivalent Weights on GlobalSpec. The weight of a compound that contains ONE EQUIVALENT of a proton (for acid) or ONE EQUIVALENT of an hydroxide (for base). • When calculating Pressure Reduction Schedule, ROUND DOWN to a whole number (for example: round down 21.6 psi/100 stks to 21 psi/100 stks).
