A student wants to compare the reactivity of an unknown metal, Q, with that of zinc. Both metals are more reactive than silver. The student is provided with: • silver nitrate solution • metal Q powder • zinc powder • a thermometer • normal laboratory equipment. No other chemicals are available. Describe a method the student could use to compare the reactivity of metal Q with that of zinc. Your method should give valid results. – 6149

1. Measure the temperature before and after adding each metal to silver nitrate solution.

   Use the same amount of metal and the same volume and concentration of silver nitrate each time.

   Make sure the starting temperature of the solution is the same for all tests.

   The metal that causes the biggest temperature change is the most reactive.
