Titration is a chemical process where a chemist finds the concentration of one solution by adding a second solution until the mixture is neutralized. 6 discussion 7 conclusion 8 references the discussion: what do your results mean the discussion section of the lab report is where the results are interpreted, especially as they relate to the goals stated in the introduction it is also a place where experimental anomalies, for example, based on the titration curve shown in figure 1, it can be seen that the titration of a strong acid with a strong base results in an equivalence point at exactly ph = 7. Precipitation titration: determination of chloride by the mohr method by dr deniz korkmaz discussion the well known mohr the titration was carried out at a ph between 7 and 10 because chromate ion is the conjugate base of the weak chromic acid (2, 3) therefore, when the ph is lower than 7, chromate ion is protonated and the chromic acid form predominates in the solution consequently, in more acidic solutions the chromate ion concentration is too.
