Final answer:
The best conductor of electricity among the options provided is 1M NaOH, as it is a strong electrolyte that dissociates into Na+ and OH- ions, enabling better conductivity compared to methanol, which is a nonelectrolyte.
Step-by-step explanation:
The student has asked which among the provided aqueous solutions is the best conductor of electricity. Given the options, the solution of 1M NaOH is the best conductor. This is because NaOH is a strong electrolyte and dissociates completely into Na+ and OH- ions when dissolved in water, facilitating the conduction of electricity. Methanol (CH₃OH), on the other hand, is not an electrolyte and does not dissociate into ions in solution, making its conductivity much lower.
Referring to data on ionic conduction, strong electrolytes like NaOH produce a high concentration of ions that conduct electricity effectively. The fact that NaOH is a 1:1 electrolyte means that the amount of current it can conduct is significant, though not as high as 2:2 electrolytes. However, since the other option presented is methanol, which is a non-electrolyte, the NaOH solution is by far the superior conductor in this comparison.
