Three experiments with an electrolyte and an anode and a cathode

Three experiments with an electrolyte and an anode and a cathode

1
Differences in voltage when adding an electorolyte to cold water and measuring voltage and adding an electrolyte to boiling water and letting it cool and testing the voltage.
 Going allong a list of electrolytes.
Important:

 The same amount of water and the same amount of elrctrolyte.

 The same sized anodes and cathodes.

2
See if there is a difference in voltage with hot, near boiling to boiling water and an electrolyte and cold water an electrolyte.
Important:

The same amount of water and the same amount of elrctrolyte.

The same sized anodes and cathodes.

Extra:
 With cold water it is important that the electrolyte is mixed wel with the water.
  Adding it to boiling water and letting it cool might be needed

3
Seeing if there is a difference in voltage between stil water with an electrolyte and constantly moving water with an electrolyte.
Important:
The same amount of water and the same amount of elrctrolyte.
The same sized anodes and cathodes.
