| What determines how Reactive a Metal is? | -It all comes down to how easy it is to lose the Outer Electrons. Easier = More Reactive |
| How can the Reactivity of Metals be shown? Use example with Magnesium, Zinc and Copper | -Simply place some Metals into Dilute Hydrochloric Acid eg
-Then, with a burning splint test, the Noise of the 'Pop' will determine how Reactive it is.
-Magnesium would have a very loud Pop, mainly because its a Group 2 Element, which are more Reactive naturally
-Zinc would have a Pop, but quieter then Magnesium
-Copper would have Nothing, its Very Unreactive
-More Reactive a Metal is - the Faster the Reaction |
| How would the Rate of the Reaction change if the Metal is more Reactive [Metal + Hydrochloric Acid] | -Faster. More reactive metals makes the Reaction more Faster, and with more Aggression
-You can also Visually see this, by the Bubble Rate, Faster Bubbles spawn in = Faster the Reaction = More Reactive Metal |
| What happens, if a Metal Reacts with Water? Show the Formula | Metal + Water --> Metal Hydroxide + Hydrogen
OR
Metal + Steam --> Metal Oxide + Hydrogen [For a Lesser Reactive Metal] |
| How can a Metal reacting with Water/Steam show how Reactive it is?
-What happens if Potassium, Zinc and Copper react with Water/Steam | -The more Violent the Reaction is, the more Reactive it is
-Potassium will react Violently with the Water, making it a Reactive Metal, which it is
-Zinc won't really do much with Water, but with Steam it can play around more [It can React with Steam]
-Copper literally will do Nothing. Easy |
| What is the Reactivity Series? | -This is simply a Table, that orders the Metals from Most Reactive, to Least Reactive. |
| Show the Reactivity Series, from Most Reactive downwards: | Potassium, K [Most Reactive]
Sodium, Na
Calcium, Ca
Magnesium, Mg
Aluminium, Al
Zinc, Zn
Iron, Fe
Copper, Cu
Silver, Ag [Least Reactive] |
| What would happen, if Iron is placed in a Solution of Copper Sulphate?
-Give the Formula | -This would become a Displacement Reaction
-Since Iron is more Reactive [Reactivity Series] it will 'Kick' out the Copper from the Sulphate, making Iron Sulphate and leaving Copper on its own
Copper Sulphate + Iron --> Iron Sulphate + Copper |
| What would happen, if Silver is placed into a Solution of Copper Sulphate?
-Give the Formula | -This would result in Nothing Happening
-Since Copper is more Reactive [Reactivity Series] it will stay on to the Sulphate, so Silver will simply just do whatever in it
Silver + Copper Sulphate --> Copper Sulphate + Silver |
