Theoretical purity

Webb28 jan. 2024 · The theoretical purity of the sample was 100. 0%, which differed with the experimental one by 1. %; the experimental purity is 101. 7%. Potentiometric titration proves to be adequate in the determination of the acid dissociation constant and purity of a sample. Aside from that, the synthesis proved adequate given the high purity of the … WebbStep 4: Calculate the percent purity. Substituting the calculated mass into the equation for percent purity gives: %purity = mass of compound mass of sample × 100 = 3.3 3.5 × (100) = 94.3% % purity = mass of compound mass of sample × 100 = 3.3 3.5 × ( 100) = 94.3 %. This section includes a recommended experiment for informal assessment.
