methods were examined in this investigation. First‚ ion-exchange chromatography was used. This method separates ions and polar molecules based on their affinity to the ion exchanger [2]. Specifically‚ cation-exchange chromatography was performed‚ a technique that uses a negatively charged ion exchange resin with an affinity for molecules with a net positive charge. Anion-exchange chromatography relies on the same principal‚ but with a positively charged ion exchange resin with an affinity

Kate Chopin is a magnificent writer who has the expertise to weave the setting of her short story‚ “The Storm”‚ in order to convey the theme.
