We will now consider the reaction of our experiment. The two half reactions for electrolysis of water are: _-) 2H₂O(l) + 2e¯¯ →>> H₂(g) + OH¯(aq) nd C) H₂O(l) → 2H+ (aq) + 1/2O₂(g) + 2e¯ The experiment is set up such that two connected funnels contain 50 mL of 0.5 M K₂SO4 and Universal Indicator. An electrode is then placed in each funnel, and an electric current is applied (Figure 1). (+) (-)
