Monica Perez Experiment 8: Acetylsalicylic Acid Experiment 01/25/2013 CHM Lab- 2211 Sec 0016 Instructor: Jennifer Reed Introduction: Commonly used as Aspirin‚ acetylsalicylic acid is an analgesic (pain reliever)‚ which is one of the products of the esterification reaction between salicylic acid and acetic anhydride. This esterification occurs since the hydroxyl group from the salicylic acid reacts with acetic anhydride to form an ester. In this experiment‚ we will be able to recreate

carry out the experiment. Firstly‚ varying the length of boiling might not be the best method to determine the amount of calcium ions. If time permits‚ I could perhaps investigate other variables such as pH‚ surface area and concentration and their effect on calcium leaching. Moreover‚ I could also use other types of fish soup stocks and compare to determine which soup has more calcium in it. Lastly‚ I have purchased “cleaned” anchovies from the supermarket to carry out this experiment‚ where the head

The aim of the experiment was to examine the effects of consuming lactate before and during a prolonged exercise. The data shows that the consumption of the lactate actually did work and the performance of the subject was better than the previous three experiments of dieting. This was due to the lactate that was consumed in the CytoMax. Azevedo‚ Tietz‚ Two-Feathers‚ Paull‚ and Chapman (2007) state that CytoMax contains polylactate which speeds up the delivery of substrates and is thought to help

Question: What is the effect of calcium in different concentrations on lima bean growth? Personal Engagement: For my internal assessment‚ I chose calcium because it interested me how adding a certain nutrient or element‚ can aid in growth of an organism. Calcium is a vital nutrient needed by most organisms and can be found in many things we consume like milk. Knowing that calcium helps keep humans healthy and have stronger bones‚ I wanted to experiment how calcium might aid in the growth of lima

the okay to do the experiment‚ I grabbed the girls and went to work. The experiment I picked was the conservation concept‚ where the idea that merely changing the appearance of objects does not necessarily change other key properties. In other words‚ just because I put the same amount of water in a bigger case‚ doesn’t change how much water there is. I predict that both the girls would fail at conservation concept‚ and always

Salinity Experiment Aim To determine a method of measuring a soil sample’s salinity level in order to measure 3 samples’ salinity level. Hypothesis I think that by running a current through a salt solution and measuring the resultant amperage‚ a pattern in the recordings will help find a soil sample’s salinity level. Variables Controlled Amount of solution (100 mL)‚ supplied voltage (4V)‚ amount of soil (50 gm) & water (150 mL) in soil sample’s solution. Independent Amps recorded

Throughout the experiments the size of the balloons stayed about the same size except for in experiment 3. Also the bottles that had more sugar had a stronger scent of alcohol and also contained more foam on top of the liquid. All yeast in each of the bottles seemed to have fermented at the same time and stopped/slowed down‚ the growing process‚ at the same time. Bottle 3 also would always overflow and the foam would fill the ballon in every experiment. Another trend with bottle 3 was that in the

Salt from green beans Name: Ashni Couprie and Dennise Susanto Class: 5c Introduction From previous experiments we ’ve learned that salt is extracted from green beans. To be more specific: salt is extracted from when the beans are cooked in water in which salt has been dissolved. This experiment is based upon the osmoses theory. According to this theory the cell walls of the green beans are what we call a semi permeable membrane. This membrane only lets water through and not the substance
