The Halogens 0.0 / 5 ? ChemistryGroup 7ASAQA Created by: elyornaisCreated on: 07-03-15 19:28 Are halogens reducing agents or oxidising agents? Oxidising agents and they get reduced. 1 of 12 What happens to the oxidising ability as we go down the group? Decreases. 2 of 12 What happens when halogens react with metal halides? The halide is displaced by a more reactive halogen (displacement reaction) 3 of 12 What is the colour of fluorine? Pale Yellow. 4 of 12 What colour is chlorine? Green. 5 of 12 What colour is Bromine? Red-brown. 6 of 12 What colour is iodine? Black solid. 7 of 12 Are halide ions reducing or oxidising agents? Reducing. 8 of 12 What happens to the reducing power of halide ions as we go down the periodic table? Increases. 9 of 12 What is the equation for sodium chloride reacting with sulfuric acid? NaCl + H2SO4 --> NaHSO4 + HCl 10 of 12 Why is the reaction of sodium chloride with sulfuric acid not a redox reaction? Because no oxidation state has changed as the chloride ion is too weak to reduce sulfur. It is an acid-base reaction. 11 of 12 What is seen when NaCl reacts with H2SO4? Steamy fumes of HCl. 12 of 12
