electrolysis experiment with variable

Does every experiment have to have an independent variable

Oct 08, 2007So is it required to have an independent variable. Does every experiment have to have an independent variable? Im doing an experimant on electrolysis of water. But my experimant does not have an independent variable cause im not changing anything..? So is it required to have an independent variable.

The electrolysis of solutions Learn Chemistry

When electricity passes through molten compounds, like sodium chloride, the ions move towards the electrode of opposite charge. Sodium chloride gives sodium metal and chlorine gas. This experiment illustrates what happens when the system is made more complicated because water is present. Electricity is passed through various solutions and the products are identified.

electrolysis copper sulfate solution with copper carbon

4. The electrolysis of copper(II) sulfate solution. The electrolyte copper(II) sulfate, provides a high concentration of copper(II) ions Cu 2+ and sulfate ions SO 4 2 to carry the current during the electrolysis process. There are small concentrations of hydrogen ions H + and hydroxide ions (OH ) from the self ionisation of water itself, but these can be ignored in this experiment.
