A student set up the apparatus shown in Figure 1 to investigate whether an electric current can pass through solid sodium chloride and through molten sodium chloride.
If an electrical current flows through the circuit, the ammeter will show a non-zero reading.
Table 1 shows the results of this investigation.
| Setup | State of sodium chloride | Ammeter reading / A |
|---|---|---|
| A | Solid | 0 |
| B | Molten | 2.5 |
Explain the results shown in Table 1 in terms of structure and bonding.
