TOTAL ALKALINITY/METHYL ORANGE ALKALINITY

1.     Apparatus

        S1/S2                :-PVC burette stand

        E1                     :- Titration Burette
 
        F                       :-Conical Flask
 
        U1                    :-Calibrated Test tube (Measuring Cylinder)

2. Reagents

       T2                      :Titrant

       A2                      Indicator

3.Test Procedure

      a.  Take 25 ml of water sample with the help of measuring cylinder T1 in conical Flask F.

      b.Add 4-5 drops of indicator A2,greenish yellow colour will appear in presence of alkalinity.

      c.Fill burette E1 with titrant T2 upto zero mark.

      d. Titrate the sample till colour changes from greenish yellow to smoky red.

4.Calculations

      Total Alkalinity = M.Alkalinity = Burette Reading is Multiplied by 4O as ppm CaCO3
