Normality . In the past, we have used for concentration. M = A more useful form of concentration for acid/base reactions is Normality. N = # eq / L # equivalents = (moles)(n) n = # of H or OH in the chemical formula. When calculating pH, normality is used over molarity but… Normality is related to Molarity…

Gram equivalent weights and normality The gram equivalent weight (sometimes called simply the "equivalent weight") of an acid is the weight in grams that will provide one mole (6.02 X 1023) of H+ ions.

A more useful form of concentration for acid/base reactions is Normality. N = Also, in calculating pH, normality is used instead of molarity. but, Normality is related to Molarity: N = Ex1: Calculate the Normality and Molarity if 1.80 g of H2C2O4 is dissolved in 150 mL of. solution.

MOLARITY (M) = • Molarity is the # moles solute per liter of solution. • The symbol [ ] is used to denote molarity of a substance. Dilution: When you dilute a solution, you can use this equation: Example: Describe how you would prepare 2.50 L of 0.665 Na2SO4 solution starting with: solid Na2SO4 b) 5.00 M Na2SO4 solution. MASS PERCENT = Example:

Conversion of Normality to Molarity and Molarity to Normality. A problem that comes up frequently is to calculate the normality of a molar solution and vice versa. To keep from getting confused, remember that #eq > #mol, and therefore N > M. For acids, N = nM, where n is the number of acidic hydrogens in the chemical formula of the acid.

= Amount of acid used to reach pH 8.3 (ml) * Normality of acid (eq/L) * 100,000 (mg CaCO3/eq) / sample volume (ml) Where Normality = Molarity (moles/L) * the number of hydrogen exchanged in a reaction (eq/moles) Ex. 2.0ml of 0.01M of sulfuric acid was required to titrate 50ml of your sample to pH 8.3.
