Reactivity series & Displacement reactions

Cards (7)

Effects of using reactants with increased reactivity in a reaction
Reaction will take place faster or more vigorously
How to investigate the reactivity of a metal using an acids
React metal with acid
When metal reacts bubbles of hydrogen will be released
Faster the bubbles are produced the faster the reaction is
How can you investigate the reactivity of metals using temperature change
More reactive metals lead to larger temp changes
React each of the metals with either water or acid
Ensure the surface area and the mass of the metal is the same
Measure the rise in temp
The greater the temp change the more reactive the metal must be
Which metals don’t react with zinc
Zinc
Iron
Copper
Why are very reactive metals dangerous in acids or water
Can be very explosive
In displacement reactions which ions are reduced
Metal ions are reduced - they gain electrons
Metal displacement reaction
When a more reactive metal displaces a less reactive metal
