Some articles on ions, hydroxide ions:

Leclanché Cell - Chemistry
... they give up both their electrons to become positively-charged ions ... As the zinc ions move away from the anode, leaving their electrons on its surface, the anode becomes more negatively charged than the cathode ... react with each other to produce manganese oxide(Mn2O3) and negatively charged hydroxide ions ...
Chloralkali Process - Procedures - Membrane Cell
... the first chamber of the cell where the chloride ions are oxidised at the anode, losing electrons to become chlorine gas (A in figure) 2Cl– → Cl2 + 2e– At the cathode, positive hydrogen ions pulled from water ... prevent the reaction between the chlorine and hydroxide ions ... disproportionated to form chloride and hypochlorite ions Cl2 + 2OH– → Cl– + ClO– + H2O Above about 60°C, chlorate can be formed 3Cl2 + 6OH– → 5Cl– + ClO3– + 3H2O ...

... Hydroxide ions, for example, when added to the solution, will react with free hydrogen ions and increase the pH of the solution ... Additionally, hydroxide ions will abstract protons from carbonic acid in solution, causing the bicarbonate concentration to increase ...
