Abstract An experiment is conducted to prepare soap and thus‚ to compare the properties of the prepared soap and synthetic detergents which are precipitation‚ emulsification and cleaning abilities. It can be concluded that soap has the properties if emulsifying oil whereas detergent has not. The abilities of forming precipitates can be seen clearly in soap solution whereas detergent forms no precipitates at all. The experiment is completed and successfully conducted. Introduction

pleasant‚ fruit-like odors and are the chemicals responsible for the odors and flavors of many fruits (oranges‚ bananas‚ pineapples) and flowers. In most cases‚ such natural products get their properties from a mixture of organic compounds. In this experiment you will prepare two esters of o-hydroxybenzoic acid‚ more commonly known as salicylic acid. One of the esters‚ acetylsalicylic acid‚ is aspirin‚ the common analgesic. We will synthesize aspirin by mixing salicylic acid with acetic anhydride. The

psychologist‚ and student of Solomon Asch‚ conducted a controversial experiment in 1961‚ investigating obedience to authority. The experiment was held to see if a subject would do something an authority figure tells them‚ even if it conflicts with their personal beliefs and morals.

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
