CHAPTER 4: CHEMICAL QUANTITIES and AQUEOUS REACTIONS
... Therefore, if the concentration of one reactant is known, we can find out the concentration another reactant required for complete neutralization. This can be measured by ‘titration’ (with the use of a chemical indicator). The point at which the indicator changes color is called ‘end point’. 3) OXID ...
