The interhalogen compound BrF3 is a volatile, straw-colored liquid. The compound exhibits appreciable electrical conductivitybecause of autoionization (“solv” refers to BrF3 as the solvent):2 BrF3(l) ⇌ BrF2+(solv) + BrF4- (solv)(a) What are the molecular structures of the BrF2+ and BrF4- ions?(b) The electrical conductivity of BrF3 decreases with increasing temperature. Is the autoionization process exothermic or endothermic?(c) One chemical characteristic of BrF3 is that it acts as a Lewis acid toward fluoride ions. What do we expect will happen whenKBr is dissolved in BrF3?

Sulfur dioxide is a common preservative in wine; it prevents oxidation and bacterial growth. When SO2 is added to wine, it reacts with water to form an equilibrium system with the bisulfite ion: SO2(aq) + H2O(l) ↔↔H+(aq) + HSO3-(aq) In this equilibrium system, SO2, is called "molecular SO2"; in its HSO3- form it is called "free SO2". Only molecular SO2 acts like a preservative. The amount of molecular SO2 in the equilibrium system is highly pH dependent. The lower the pH, the more the equilibrium shifts to the left and the greater the amount of free SO2 is present. (it favors the reactants). The recommended amount of free SO2 is 0.8 ppm for white wine and 0.5 ppm for red wine. The table below shows the amount of free SO2 required to obtain the correct amount of molecular SO2 as a function of pH for both red and white wine. For dilute solutions such as these, 1 ppm = 1 mg/L. Using the table values, answer the following questions. Table: Amount of free SO2 required to maintain…
