AQA A Level Chemistry 2017: Paper 1 Inorganic and Physical With Correct Elaborated Answers
Define the term enthalpy of lattice formation The standard enthalpy change when 1 mole if solid ionic compound is formed from its gaseous ions. Explain why a value for enthalpy of lattice formation of silver iodide based on the perfect ionic model gives a smaller numerical value than the value calculated in the question AgCl contains covalent character Forces/bonds holding lattice together are stronger Identify a reagent that could be used to indicate the presence of iodide ions in an aqueous solution and describe the observation made Reagent: AgNO3 Observation: yellow ppt forms
