Q

What is the reactivity series based on

A

How easily metals form positive ions

The more easily it forms positive ions, the more reactive

Q

How to find order of reactivity series from experiment

A

Compare the relative reactivity of different metals with either an acid or water and put them in order

You can measure the temperature change of this reaction with an acid or water over a set period of time. If you use the same mass and surface area of metal each time, the more reactive the metal the greater the temperature change should be

Q

How can you work out reactivity of metals with acids

A

By monitoring the rate of hydrogen production when they react with an acid
The more reactive the metal, the faster the reaction will go
The speed of the reaction is indicated by the rate at which bubbles of hydrogen are given off

Q

What metals can be extracted by reduction using carbon

A

Metals less reactive than carbon

17
Q

Why can only metals less reactive than carbon be extracted with reduc

A

Because carbon can only take the oxygen away from metals which are less reactive than carbon itself

18
Q

How can metals more reactive than carbon be extracted

A

With electrolysis
