With reference to ionic compounds, consider the following statements: 1. Ionic compounds are insoluble in alcohol. 2. Ionic compounds in the solid state are good conductors of electricity. Which of these statements is/are correct?

Statement 1 is correct: ionic compounds are stabilized by strong interionic attractions and typically dissolve well in highly polar solvents like water; they are generally poorly soluble in less polar organic solvents (such as many alcohols) because those solvents cannot sufficiently solvate and separate the ions [1]. Statement 2 is incorrect: in the solid state the ions are held fixed in a crystal lattice and cannot move freely, so solid ionic compounds do not conduct electricity. Ionic conductivity appears only when the lattice is broken and ions become mobile, e.g., in molten salts or in aqueous solution [2].
