Indicator;  are weak acid or base dyes whose colors are sensitive to ph, or hydronium ion conccentration.

Titration;  Is the controlled addition and measurements of the amount of a solution of known concentration that is required 
to react completely with a measured amount of a solution of unknown concentration.

Standard Solution;  a solution that contains a precisely known concentration of a solute.  

Equivalence point;  the point at which there are equivalent quantities of hydronium and hydroxide ions in a neutralization 
reaction. 

 End point;  The point in a titration where an indicator changes color.
