AP Chemistry
2.3 Structure of Ionic Solids
A student tests the electrical conductivity of a pure sample of \(\text{KCl}\) in two different states: as a crystalline solid at \(25\ ^\circ\text{C}\) and as a liquid at \(800\ ^\circ\text{C}\) (above its melting point of \(770\ ^\circ\text{C}\)). Which of the following statements correctly compares the electrical conductivity of the two samples and provides the best particulate-level justification?
