Extraction and analysis of two compounds from unknown solution C ABSTRACT Liquid C and solid C were both extracted from unknown solution by first using chemically active liquid-liquid extract‚ followed by vacuum filtration. Liquid C and solid C were then purified with the use of simple distillation and recrystallization respectively. Through the process of recrystallization‚ the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119

Preparation of an Ionic Compound from Aluminum Metal October 6‚ 2010 The purpose of this laboratory project was threefold‚ in that it presented three main objectives. The first objective was to prepare the ionic compound alum from aluminum powder. The alum was produced from the reduction-oxidation reaction of aluminum with potassium hydroxide and sulfuric acid in water. The second objective was to then analyze the alum product for water crystallization; that is‚ to determine the value of x in

EXTRACTION OF COPPER FROM OXIDISED COPPER ORE Aim: To analyse how copper is obtained from oxidised copper ore using the processes of leaching‚ solid-liquid separation‚ displacing and electrowinning. Method: Refer to ‘Extraction of Copper from oxidised Copper Ore’ document pages 1-2 Results: Leaching: The blue particles in the copper ore which is copper was dissolved in the sulphuric acid and the solution turned into a blue colour. There was also sediment that was floating around

Experiment 2 Acid/Base Titration John J. Purdue CHM 321 – Fall 2012 TA: Scott Cole Section 1 September 4‚ 2012 Unknown Concentration: X.XX ± X.XX M (@95% confidence interval) (adapted from a report prepared by N. Skrynnikov‚ 2009) Abstract The concentration of an unknown acid (HA) solution was determined by titration with a standardized solution of sodium hydroxide. The standardization of NaOH was done by titration with a solid acid sample‚ potassium hydrogen phthalate (KHP)‚ and phenolphthalein

Why do some liquids flow more freely than others? Liquids vary in their viscosity (resistance to flow). A definition of viscosity; “Viscosity is a measure of a fluid’s resistance to flow. It describes the internal friction of a moving fluid. A fluid with large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion. Gases also have viscosity

The liquids I will be using in the experiment to test this question is coffee‚ Coke‚ tea. Some people have more stained teeth then others‚ and that is affected by their diets. Different liquids can to different things to your teeth‚ and the most frequent thing done to teeth is staining. The reason for this project is to test what different liquids stain the teeth the most‚ so that people can prevent their teeth standing by not drinking as much of certain liquids. The next

3.3. Characterization of the S2 VNP loaded liquid SNEDDS 3.3.1. Assessment of self-emulsification efficiency The emulsification time for S2‚ which is the time needed for SNEDDS to form homogeneous transparent mixture upon dilution‚ was 12 sec when 1 gm of VNP SNEDDS was added to 200 ml of 0.1 N HCl. When the same experiment was performed but by using 500 ml distilled water‚ the time required for the complete disappearance of SNEDDS was 14 sec. The emulsification in both media is under grade A of

Extraction of Caffeine from Tea Leaves Santos‚ Raphael‚ Samson‚ Nonia Carla‚ *Tabora‚ Brylle‚ Tan‚ Kate Michal Department of Biological Sciences‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Tea leaves are natural products that are harvested from agriculture. Caffeine‚ on the other hand‚ is a stimulant that has been shown to speed up the time of reaction‚ increase alertness‚ and improve one’s concentration. What we did in this experiment was to extract the alkaloid caffeine content
