|  | 1. | Usually, the only result of interest is the equivalence point. 
 
 | 
|  | 2. | The titration curve can be used to graphically determine the equivalence point. 
 
 | 
|  | 3. | Both equivalence points are visible . ]] 
 
 | 
|  | 4. | Prior to the equivalence point, the solution contains I  " but little I 2. 
 
 | 
|  | 5. | Therefore, the alkalinity is modeled and quantified with respect to the CO 2 equivalence point. 
 
 | 
|  | 6. | Thus the pH will equal the pK a which occurs half-way to the equivalence point. 
 
 | 
|  | 7. | At the equivalence point, excess I 2 appears and an abrupt voltage drop marks the end point. 
 
 | 
|  | 8. | Between the two buffer regions there is an end-point, or equivalence point, at about pH 3. 
 
 | 
|  | 9. | This continues until the equivalence point is reached, at which one obtains a solution of sodium chloride, NaCl. 
 
 | 
|  | 10. | In a titration of an acid with a base, the point of neutralization can also be called the equivalence point.
