The deflection occurs because the circuit becomes complete since free ends of the tester are dipped in a solution. The solution is certainly a conducting solution. This is the reason why the compass needle shows a deflection

Answer 2

Answer:

Yes, the solution does conduct electricity. Compass needle shows deflection due to magnetic effect of electric current.
