Normality is a useful parameter to indicate the strength of the solutions based on the activity of their constituents. It is … Ver mais The normality of a solution can be found via several methods, the best and the most convenient of which is to treat the solution (with unknown concentration) against a standard … Ver mais When to use normality? It is used in lab standard procedures where active species are involved. How is the molarity of a percentage solution calculated? The Molarity of the percentage solution is given by, M = (% purity x … Ver mais The comparison between normality (N) and molarity (M) is much similar to that of molarity (M) and molality (m). Normality (N) is the number of gram equivalents of solute dissolved per liter of solution, whereas, molarity is … Ver mais WebSodium Thiosulfate (Na2S203) - Sodium thiosulfate is a colorless, transparent monoclinic crystal widely used by utilities for dechlorination. Visit BYJU’S to learn about the Physical and Chemical Properties of Sodium … Web7 de abr. de 2024 · N = 316 × 1 248 × 250 × ( 10 − 3 L) = 5.09 N Therefore, the normality of the solution formed by dissolving 316 g of sodium thiosulphate in water is 5.09N. Additional information: Often the normality is used to measure the reactive capacity of the molecule, for the equivalence factor (n) is considered. notf-3612
