Among these is the ‘self-sealing’ property or surface precipitation reaction. When a cell is broken, its contents do not diffuse into the surrounding medium but instead form discrete droplets.

Below is an example of a precipitation reaction. Notice the two aqueous solutions make a solid substance. \(AgNO_{3}(aq) + NaCl(aq)\rightarrow AgCl(s) + NaNO_{3}(aq)\) If state symbols are not ...
