The % relative standard deviation (% RSD) was found to be below 5 % for all the four analytes in system precision and below 6 % in method precision. The data as shown in Table 3.4.3.3.3 and 3.4.3.3.4. LOD values observed for Hydrazine carbamate and Hydrazone carbamate were 0.0018 µg per mL and 0.00092 µg per mL respectively. The LOD value observed for both 1-Hydroxy benzotriazole and 2R, 3S Chlorohydrine hydrochloride were 0.0019 µg per mL. The LOQ values observed for all four analytes were 0.0037 µg per mL. The data as shown in Table 3.4.3.3.5 and 3.4.3.3.6.

    Isolation of Component Via Extraction Objective: Separation of organic acid from a neutral compound using liquid/liquid extraction. Experimental: Similar to the “Thin Layer Chromatography” experiment, a TLC plate was ran with 2 ml of EtOAc and 8 mL of hexane in the jar. The Rf value was calculated using the formula located in the data for all the TLC plate. The mixed compound that was dotted on the TLC plate had 0.300 g of the impure benzoic acid and 10 mL of dichloromethane. A 50 mL flask was weighed and recorded.…

    The molar mass of KHP was 204.22g. Molarity x Volume (L) = Moles of KHP Moles of KHP x Molar Mass of KHP = grams of KHP 0.1 x 0.05 = 0.005 moles of KHP 0.005 x 204.22 = 1.0211 g KHP Dilution of NaOH and HCl To find out how to dilute NaOH and HCl the equation M1V1 = M2V2 is used. For both the M1 and V1 were given as 0.1 and 250 mL respectively. The M2 was given as 3. The equations were set up as follows: g HCL = 0.1 x 250 = 3 x V2 → (0.1 x 250)/3 = V2 = 8.3 g HCl g NaOH = 0.1 x 250 = 3 x V2 → (0.1 x 250)/3 = V2 = 8.3 g NaOH Preparation of Ascorbic Acid Solution The vitamin C tablet was crushed and 0.5 grams of ascorbic acid was mixed with 50 mL of deionized water to form the Ascorbic Acid Solution Preparation of NaHCO3 solution The baking soda was measured to 0.5 grams and was mixed with 50 mL of deionized water to form the Sodium Bicarbonate Solution.…
