Witryna7 kwi 2024 · In the crystallized solid's H 1 NMR spectrum (Figure 3.6b), the benzoic acid signals are entirely gone, demonstrating that the crystallization successfully purified the p -bromobenzoic acid. An analogous purification could be done if a bromination reaction produced a mixture of m -bromobenzoic acid and benzoic acid. WitrynaOverview. Recrystallization is a technique used to purify solid compounds. 1 Solids tend to be more soluble in hot liquids than in cold liquids. During recrystallization, an impure solid compound is dissolved in a hot liquid until the solution is saturated, and then the liquid is allowed to cool. 2 The compound should then form relatively pure ... crown 4 300
