Web15 de set. de 2024 · Uses of Normality. It is used in acid-base chemistry to determine concentrations. For example, the presence of compound ions such as hydronium ions (H 3 O +) or hydroxide ions (OH –) in a solution is clearly the result of normality.; The number of chemical ions that are likely to precipitate in a particular reaction is determined in … WebUses of Normality. Normality is used mostly in three common situations. In determining the concentrations in acid-base chemistry. For instance, normality is used to indicate hydronium ions (H 3 O +) or hydroxide ions (OH –) concentrations in a solution.; Normality is used in precipitation reactions to measure the number of ions which are likely to …
