The first step in the titration process is; A measured volume of an acid or base of (un)known concentration is added to a flask. The second step is several drops of indicator are added to the solution, and the third step is ; the measured volumes of a base or acid of known concentration are added, using a burette, until the indicator just barely changes color (end point or the equivalence point).
Scientist have learned by studying seismic waves that the earth has liquid in its outer core. They also can predict if a earthquake might happen in a spot in the next hundred years or so.
