pipette. The mixture was stirred at high speed. The mixture turned cloudy and white. The temperature was 3. The mixture was then poured through a Buchner funnel using vacuum filtration. The water and succinimide (the other product formed) collected in the flask below the funnel. This was the filtrate. BCHA stayed on top of the filter paper in the funnel. This was the precipitate. It was observed as a white powder. A beaker was pre-weighed at 14.40 g. The beaker was labeled and then the precipitate was

Separation by difference in particle size: Sieving: - Is a way pf separating mixtures of solids‚ or solids and liquids with different sized particles - The mixture is poured through a sieve and the particles smaller than the sieve pass through while the larger particles are trapped by the sieve - The are commonly used for cooking - E.g. a mixture of rice and water is poured through a sieve to capture rice and remove the water Filtration - Is a technique commonly used for mixtures of solids and liquid

Introduction Eugenol is a naturally occurring chemical that has medical applications such as its use as a natural dental anesthetic. It can be extracted from cloves by using the method of steam distillation. The extracted compound will then be separated from the water using methyl chloride‚ which will then be evaporated using a rotary evaporator leaving only the essential oil‚ Eugenol. IR spectroscopy will be used to determine the structure of the extracted compound. Results and Discussion Four

Factors that affect how the PH changes during a titration experiment. Concentration of the alkali Having a higher concentration of alkali will mean that there will be more molecules closer together for the acid to collide with. This will speed up the reaction as collision theory suggests that molecules have to collide to react and if there are more molecules to collide with the reaction will happen faster as there is a higher chance of a collision. Volume of alkali An increase in volume would mean

Experiment 7- Isolation of the Major Component of Clove Oil Pre-Lab Questions: 1.) Briefly explain the concept of steam distillation. What is the difference between a simple distillation and a steam distillation? When a mixture of two immiscible liquids are distilled it is referred to as codistillation. This process is referred to as steam distillation when one of the liquids is water. This distillation is used to separate organic liquids from natural products and reaction mixtures in which

Place a sheet of filter paper inside the funnel and place the funnel on top of the Erlenmeyer flask. Pour the beaker with the combination of water and mixture slowly into the funnel until all water is filtered through; leaving only the solid components behind. The remaining solids should now be poured into a beaker‚ and added with 50ml of water measured with graduated
