Electrolysis and electroplating
How could we measure these?!
You need to develop your own hypothesis to investigate a factor that may affect the mass deposited on the negative electrode during electrolysis.
You will need to produce your own hypothesis and research a plan.
You will need to reference (name) two sources that you used for your research. One of these sources must be a method.
Where could we find information to help us with this problem?
Possible search questions:
These could be found in:
You will need to write up your research on the ‘candidate research form’. You can gather the information in your books and then complete the form neatly.
Extension: which of the two sources was the most useful and why
You must explain which one of your sources of information is the most useful.
You must comment on both, such as…
Source 1 gave me a complete method of what to do. Source 2 gave me information about how solar cells work and what affects how much voltage they make.
