WebJan 25, 2014 · The order of reactivity of the 4 metals from the most reactive to the least is magnesium, zinc, iron and copper. 1. We used mainly 2 criteria to determine the rate of reaction: The change in temperature of the test tube, and the amount of bubbles being released from and covering the surface of the metal. 2. Web2 years ago. Undiluted acids are very dangerous. Concentrated HCl or Concentrated H2SO4 will react VERY vigorously with the metal. The reaction with concentrated acids is highly exothermic (releasing heat). The H2 gas that is produced as a result of the reaction might get ignited by the heat, and burn violently. WebNov 2, 2024 · The reactivity series is a series of metals, in order of reactivity from highest to lowest. It is used to determine the products of single displacement reactions, whereby metal A will replace another metal B in a solution if A is higher in the series.
