Sulphuric Acid Production Should Not Be Banned Background Information Acids and bases are chemical compounds with certain properties, and are classified according to several different definitions. There are clear distinctions between the two types of compounds, and although they share some similarities in their physical and chemical properties, their uses and applications vary greatly. Acids can be described as having a sour taste, producing hydronium ions in water, forming a salt and water when reacted with a base and having a pH of less than 7. In contrast, bases follow the descriptions that; they taste bitter, produce hydroxide anions in water, feel soapy & slippery and have a pH of more than 7. There are three chemistry-based…show more content…
1. Strong acid + strong base  Salt + water e.g. HNO3 + LiOH  LiNO3 + H2O In this reaction, the products are always a salt and water. The salt, in a reaction between a strong acid & a strong base, always has a pH of 7.00. The produced ions will not react with the H2O. 2. Strong acid + weak base  Salt e.g. H2SO4 + NH3  (NH4)2SO4 Usually, reactions between strong acids and weak bases do not result in water being formed, and instead only a salt is produced. This is because weak bases usually do not have hydroxide ions. 3. Weak acid + strong base  Salt + water e.g. HNO2 + NaOH  NaNO2 + H2O The reaction between a weak acid and a strong base results in the production of a basic salt, i.e. a salt with pH > 7, and water. 4. Weak acid + weak base  Salt e.g. HNO2 + HN3  NH4NO2 “The pH of the solution formed from the reaction of a weak acid with a weak base depends on the relative strengths of the reactants. For example, if the acid HClO has a Ka of 3.4 x 10-8 and the base NH3 has a Kb = 1.6 x 10-5, then the aqueous solution of HClO and NH3will be basic because the Ka of HClO is less than the Ka of NH3.” (Helmenstine, 2004) Production of Sulphuric Acid Sulphuric acid, in its anhydrous form, cannot naturally occur on Earth; however, the natural formation of sulphuric acid does occur, rarely, in a few different circumstances. One natural occurrence of sulphuric acid happens due to the sulphur dioxide gas produced by volcanoes. Sulphur
