Titration is an analytical technique which allows the quantitative determination of a specific substance (analyte) dissolved in a sample. If you want to simply calculate the acidity of your analyte with the titration method, then you are expected to use a neutralizing alcaline solution for the process. Close the stopcock immediately and wait for 30 seconds. The concentration of analyte may then be calculated using the formula: C a = C t V t M / V a This lets us quantitatively analyze the concentration of the unknown solution. During the titration of strong acid with strong base the pH changes from 3 to 11, phenolphthalein indicator range from pH 8 to 10 that’s why mostly used for this type of titration. This is why you need to carry out a standardization. The mechanism of titration is neutralizing the nature of your analyte so that the indicator you used changes color, that way, you can calculate how much neutralizing solution (and active substance) you have got to use, this way you can calculate the actual volume of let's say acidity level, referring to above example, there is in your sample (analyte). A standard solution of a reagent of known concentration is called the titrant or titrator. Titrant is dripped into the analyte and indicator solution until the reaction between titrant and analyte is complete, causing a color change (the endpoint).
