This chart illustrates the ranges of color change for several acid-base indicators. Titration curves help us pick an indicator that will provide a sharp color change at the equivalence point. The best selection would be an indicator that has a color change interval that brackets the pH at the equivalence point of the titration.

Thus 1 mole of HNO3 has 1 eq of H+, 1 mole of H3PO4 has 3 eq of H’", and 1 mole of Mg(OH)2 has 2 eq of OH‘. Why have chemists defined equivalent? The answer to this question is present in the word used: “equivalent.” In an acid base reaction, one equivalent of any acid exactly neutralizes one equivalent of any base. Equivalent Weight of an Unknown Acid Top. Objectives. To find the equivalent weight of an unknown acid. Discussion. By definition one equivalent (or equivalent weight) of a substance is the amount of that substance which supplies or consumes one mol of reactive species. Instructions. This program determines the molecular mass of a substance. Enter the molecular formula of the substance. It will calculate the total mass along with the elemental composition and mass of each element in the compound.

Name:__Grading key _____ Page 5/9 Question 4 (7 points) deals with your titration of 0.202 g of an amino acid with the molecular formula C5H9O4N. The end point occurs when you have added 27.50 mL of 0.100 M NaOH. You determine that the equivalent weight of the amino acid is 73.54. A. Nov 13, 2015 · To calculate the molar mass of a compound, multiply the subscript of each element from the formula times the molar mass of the element. The molar mass of an element is its atomic weight (relative atomic mass) on the periodic table in g/mol. Equivalent weights may be calculated from molar masses if the chemistry of the substance is well known: sulfuric acid has a molar mass of 98.078(5) g mol−1, and supplies two moles of hydrogen ions per mole of sulfuric acid, so its equivalent weight is 98.078(5) g mol−1/2 eq mol−1 = 49.039(3) g eq−1.

  • equivalent weight of the alloy is proportioned to the sum of the elemental weight fractions. For example, the electrochemical equivalent of Type 304L stainless steel is: k304L = 0.71 kFe + 0.19 kCr + 0.09 kNi where = ram atomic weight (Number of outk shell electrons) (96,500) and Fe is assumed to lose two electrons, Cr three, and Ni two.
  • Another way of expressing this is that the equivalent weight is defined as the mass (in grams) of a base that reacts with exactly 1 mole of hydrogen ions (H +). Because 1 mole of acid or base is equal to 1 equivalent of acid or base, equivalent weight is expressed in grams per equivalent (g/equivalent or g/eq) (Equation 2).
