It will also help you plan for an appropriate response when spills do occur. In the case of sodium bicarbonate reacting with sodium hydroxide, hydrogen ions formed by the dissociation of bicarbonate are removed by reaction with hydroxide ions to form water, causing the equilibrium to shift to favor greater dissociation of bicarbonate, driving the reaction to completion. Mercury spills rarely present an imminent hazard unless the spill occurs in an area with extremely poor ventilation.
