Aqueous Solutions Reactions‚ Metathesis (Double Replacement) Reactions and Net Ionic Equations Terrance Shelton Introduction India’s cultural treasure and biggest tourist attraction is slowly losing its magnificent appeal due to decades of acid rain. The walls of the Taj Muhal are composed of a marble-like substance ( CaCO3) that corrodes and eventually crumbles when reacted with acid rain(H2SO4). Not only is the Taj Muhal suffering‚ but also other historic landmarks across the world. This is

was able to pass all of them. I recommend using sodium carbonate as your substance. Of all the substances‚ only two were covalent and two were ionic. The ionic substances‚ sodium chloride‚ sodium carbonate‚ and salicylic acid‚ came close to the description you requested. The covalent substances‚ sucrose and salicylic acid‚ did not match the descriptions. The best substance would definitely be sodium carbonate‚ since it passed all the tests. Sodium carbonate had a high melting point‚ so it will be

36100 Introduction The purpose of this lab was to produce benzoic acid by mixing sodium benzoate with hydrochloric acid. The Hydrochloric acid used in the experiment was a stock solution made by mixing HCl Acid and deionized water. HCl acid‚ historically called‚ muriatic acid or spirits of salt‚ hydrochloric acid is produced from sulfuric acid and common salt‚ NaCl (Princeton.edu). Since the early 1900 ’s‚ sodium benzoate has been used as a food preservative (SolarNavigator). It is utilized in

Goals The main goal of this project is to learn how to identify the properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound‚ and compare them for cost effectiveness

Introduction. The following is an experiment into temperature change in an exothermic reaction taking place between Sodium hydroxide (NaOH) and Hydrochloric acid (HCl) and also how the concentration of the acid will vary these results. The characteristics of the reaction feature a neutralisation‚ an energy change (shown as a temperature change) that is usually exothermic (gives out heat). The reaction of neutralisation is exothermic because of the bonds being broken and made in the reaction. When
