WebThe sodium thiosulfate reacts with elemental iodine to produce sodium iodide. At the moment that all of the elemental Iodine has been converted the solution turns from yellow to clear. A starch indicator is used to capture the dramatic color change at the endpoint. The reaction is as follows: 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
