Electrolysis of water lab answers

Some of the water will ionise, that is, turn to hydrogen (H +) and hydroxide (OH –) ions. When the sodium chloride is dissolved in water, the ions forming the ionic solid separate out. This means that there are actually 4 ions present in the solution: H +, OH –, Na + and Cl –. The negative ions are attracted to the positive electrode. The ideal electrolyte of water electrolysis is one that does not appreciably interfere with the electrolysis process. From a purely theoretical standpoint, almost all electrolytes that induce ionisation in water can be used. When these ionic agent... If you do not care about the water being clear, graphite is a good alternative, as it only tends to This is the ideal metal since it doesn't corrode at all under the conditions used for electrolysis. I'm not a chemist and I tried Googling it but unfortunately did not see an answer that was relevant for me.

Electrolysis of water lab answers. $\begingroup$ @Mathelogician Electrolysis of water is not an equilibrium process to start with. If you supply current, you'll split water, if you don't you don't.
