Week 10: Oxidation and Reduction Reactions: The Reactions of Copper Data: Part I: Preparing a solution of copper (II) nitrate Initial mass of copper wire: .520g Mass of copper wire after vigorously scouring: .518g Observations of Copper (II) ribbon mixed with HNO3: Solution turned green. Thick brown gas formed. Copper (II) bubbled vigorously. Cu (II) dissolved‚ solution appeared green/blue. After the addition of H2O a blue crusty precipitate formed. Part II: Synthesis of solid copper

Sodium is a metal from group 1 of the periodic table‚ this is a metal which reacts when it needs to‚ this metal has a low melting and boiling point‚ also it is very dense‚ this shows that when reacting with other substances it will be different and this is because it will not react the same the whole time. The other thing is that this elements electron configuration is 11 which is quite low when comparing them to the other elements in the periodic table. However this metal is more reactive than

The aspects of using tobacco are influenced and determined by individual factors such as self-image and perceptions‚ social factors such as the societal norms‚ environmental factors such as economics and advertising‚ the traditional use of tobacco as a cultural factor‚ acculturation alongside the historical context of the tobacco industry in different communities. Both the patterns and behaviors on the use of tobacco have led to the difficulties in both its measurement and study. Nevertheless‚ the

analysis Introduction Aspirin‚ which is also known as acetylsalicylic acid. C9H8O4 is the chemical format for Asprin. The chemical structure of aspirin: Aspirin is anti-inflammatory. Aspirin is prepared by chemical synthesis from salicylic acid‚ by acetylation with acetic anhydride. The fact that it is an acid allows us to quantify the amount of aspirin in a solution. We would do this by by using an acid-base titration. Sodium hydroxide (NaOH) will be used In this experiment as the base. Preparation

Lab 1: Acid/Base Properties of an Antimicrobial Agent 09/03/13 Purpose The purpose was to determine the acid and base properties of the antimicrobial agent sodium benzoate. Theory Sodium has mainly been used in food processing to avoid growth of bacteria and harmful microorganisms. It is commonly used to preserve foods and beverages that have an acidic pH. Rather than benzoic acid‚ sodium benzoate is used because it is generally soluble in most aqueous solutions but benzoic acid is not
