Normality sample problems
Web18 de ago. de 2024 · H 3 AsO 4 + 2 NaOH → Na 2 HAsO 4 + 2 H 2 O. If you look at the reaction, you see only two of the hydrogen ions in H 3 AsO 4 react with NaOH to form the product. So, there are 2 equivalents and not 3 like you might expect. You can find normality using the equation: N = Molarity x number of equivalents. N = 1.0 x 2.
