Question

question 9 (1 point) listen to determine if the metal salt contains paramagnetic or diamagnetic ions, the first step is to... a) tare the balance with the metal salt vial on the balance. b) place the magnets on the metal salt vial. c) measure out a sample of the metal salt into a weigh boat. d) mix the first two vials to create the metal salt. e) tare the balance with the rubber stopper and magnets on the balance.

Explanation:

To determine if metal - salt contains paramagnetic or diamagnetic ions, we need to interact with a magnetic field. Placing magnets on the metal - salt vial will allow us to observe if there is an attraction (paramagnetic) or repulsion (diamagnetic) due to the presence of unpaired electrons in the ions. The other options are related to weighing or sample preparation and not directly to the magnetic property determination.

Answer:

B. place the magnets on the metal salt vial.
