A reagent, called the titrant or titrator,[1] of a known concentration (a standard solution) and volume is used to react with a solution of the analyte or titrand,[2] whose concentration is not known. Using a calibrated burette or chemistry pipetting syringe...

  • Analysis of Bleach

    Redox Titration Analysis of a Commercial Bleach Purpose To perform a redox titration. To determine the amount of hypochlorite ion present in commercial bleach. Introduction Many commercial products, such as bleaches and hair coloring agents, contain oxidizing agents. The most common oxidizing agent in bleaches is sodium hypochlorite, NaClO (sometimes written NaOCl). Commercial bleaches are made by bubbling chlorine gas into a sodium hydroxide solution. Some of the chlorine is oxidized...

  • Science Assignment on Vinegar Titration

    looking for consistency in the amount of base used. The reason for three tests for each acid is to get the most accurate amount of base, to neutralise the acid. 1.2 Aim To determine the concentration of acetic acid in some commercial vinegars by titration against a standard sodium hydroxide solution. 1.3 Hypotheses It is hypothesised that as the volume of vinegar is increased, the amount of sodium Hydroxide required will neutralise will the acid to change it to a pale pink. Method 2.1 Materials ...
