From the experimental results of sulphuric acid 0.1 n standardization found that the weight of sodium carbonate (g) used in the analysis, a is equal to B & g 0.1509 is equal to 0.1598 g. Volume of sanfiorik acid (ML) that is used in the analysis, a value equal to 16.3 ml and b is equal to 16.5 ml. Sanfiorik acid volume (ML) that is applied to the sample (blank) 0.1 ml is equal to a and b is equal to 0.1 ml portion of net volume sanfiorik acid (ML) 16.2 ml is equal to a and b is equal to 16.4ml and the concentration of sanfiorik acid (n) a is equal to 0.176 n and b is equal to the average value of 0.185, n concentration sanfiorik acid equals 0.1805.
