Volumetric flask

as to change focuses and densities as tock arrangement. Materials and Methods: The motivation behind this lab was to pick up experience utilizing different devices of estimation. The metric ruler, the advanced gram scale, the graduated barrel, volumetric cup and serological pipet were all used to catch estimations of different…

Brandon Ugbesia 9/24/2015 Steps and Procedures 1. Blend a 120 g sample of each fruit separately a in a blender with about 50 mL of distilled water. Strain any extra pulp with a cheesecloth. You should have at least around 120 ml of substance. 2. Separate each of the liquids into half and put each half into its own separate individual…

This study involves the use of redox titration to determine the amount of oxalic acid in the sample solution. The analyte solution containing oxalic acid was added with sulfuric acid and heated prior to the titration with permanganate. The persistent pink color signaled the end of the titration. The amount of the oxalic acid in the solution was found to be 8.941%. The redox titration was precise in the quantification of oxalic acid with a standard deviation of 1.327%. Introduction One of the…

Abstract: A simple, novel, and sensitive method developed for estimation of Dappagliflozin and Saxagliptin. The method was carried out on reverse- phase C18 inertsil column, with mixture of Methanol: Water ( 80:20) ratio as a mobile phase, 1 ml / min flow rate. Different analytical parameters such as linearity, precision, accuracy, Limit of detection (LOD), Limit of Quantification (LOQ), robustness were determined according to the International conference on Harmonization ICH guidelines. The…

into a solution of 6ml of 5M of NH4OH and 200ml of water. Solution was transferred to 250ml volumetric flask. Ph was adjusted to 8-9 by adding 6 drops of 10% ammonium citrate. 1ml of solution was dispensed from a burette. 2ml of 10% ammonium citrate and 10ml of deionised water were added. 10 drops of 5M of NH4OH and 3ml of 0.1% cuprizone solution were added. Solution was transferred to a 25ml volumetric flask, UV-VIS absorption spectrum of 400-700nm was carried out and absorbance were measure at…

Introduction: Acetaminophen is a common pain reliever and fever reducer used to treat conditions such as head, muscle or tooth ache, as well as colds, fevers, and even arthritis. It is available in a tablet form to be ingested. These tablets are manufactured by a large variety of pharmaceutical manufactures including a great deal of generic brand companies. These tablets all have the same active ingredient, acetaminophen, yet each hold different inactive ingredients that can impact the overall…

solution upwards. This equilibrium point will be used to determine the height of the rise of the solution, which is a factor in determining the surface tension of the solution. Different concentrations of n-butanol solution were prepared in volumetric flasks. Then the radius of the capillary tube was identified by performing the capillary rise method using deionized water. With the given surface tension of water at 30 degrees Celsius, the radius was calculated:…

using a rubber stopper. The flask is then left overnight at a temperature of about 30oC. The next morning the flask is left to cool to room temperature and the rubber stopper is carefully removed and the sample holder carefully discarded. The walls of the flask are rinsed with distilled water and 1mL of potassium iodide solution is added. The flask is swirled to mix the solution. Blank solutions are prepared by adding 10mL of acid dichromate solution to a conical flask, 100mL of water and 1mL of…

Use a 20ml volumetric pipet to measure the required volume of decarbonated soda and put it in a 250ml beaker. Add distilled water using a graduated cylinder. Place pH probe in the soda solution. Put beaker on a magnetic stir plate (keep probe away from the stirrer).…
