Ingredients in Cigarette Stearic Acid is a waxy white substance that is a fatty acid. It is found in nature in animal and vegetable fats‚ and is a component that is used to make candles‚ plastics‚ oil pastels‚ and cosmetics. Stearic acid is also used in lubricating mixtures‚ waterproofing materials‚ varnish driers‚ and as an emulsifying agent. It’s addictive‚ however it is non-toxic. A study which was done in Sweden shows that Stearic acid is a risk factor for breast cancer. Stearic acid is used

Theory The first experiment focused on the concept of errors and uncertainties that are obtained during measurements. For an experiment to be successful‚ especially those that involve measurements‚ the number of significant figures must be known. Significant figures are the digits required to express a measured quantity and thus reflect the accuracy of the measurement. Uncertainty is defined as the smallest increment that can be measured and is defined by the instrument used. An error is defined

Introduction Wrong or inaccurate measurements can lead to wrong decisions‚ which can have serious consequences‚ costing money and even lives. The human and financial consequences of wrong decisions based on poor measurement being taken in matters as important as environmental change and pollution are almost incalculable. It is important therefore to have reliable and accurate measurements which are agreed and accepted by the relevant authorities worldwide. Metrologists are therefore continuously

aspirin Intro- Aspirin is known as a pain reliever for muscle ache‚ head ache and can prevent heart attacks as well as blood clots‚ and many more things that it can help with. Aspirin is known as Acetylsalicylic acid (ASA) is a Salicylate. Salicylates are organic acids from plants that people for hundreds of years have been used for pain reducing. Salicylic acid irritates the stomach when consumed so German scientist Felix Hoffman suggested ASA as an alternative. Aspirin is made when Acetic Anhydride

to synthesise pure aspirin using chemical tests such as esterification and recrystallization independently and to also find out the melting point range of aspirin using melting point determination. INTRODUCTION Aspirin‚ which is also known as acetylsalicylic acid‚ is one of the commonly used and widely found in any drugstore or pharmacy. Its properties make aspirin a well-rounded drug that reduces inflammation and fever and also relieves pain. The active ingredient in aspirin was found to be salicylic

Commercial Aspirin Tablet Analysis Tuesday Evening Intro: The purpose of this lab was to analyze commercial aspirin tablets. To do so‚ the percent acetylsalicyclic acid (active ingredient) in tablets using acid-base titration was determined‚ the percent acetylsalicyclic acid in tablets by formation of a colored iron(III)-salicylate complex was determined using spectrometry‚ and then the percents from each process was compared. Acetylsalicylic acid is produced when salicylic acid and acetic

IB1 Chemistry Practical #8 ANALYSIS OF ASPIRIN TABLETS For a long time the bark of the willow tree (salix alba) was used as a traditional medicine to relieve the fever symptoms of malaria. In the 1860’s chemists showed that the active ingredient in willow bark is salicylic acid (2-hydroxybenzoic acid) and by 1870 salicylic acid was in wide use as a pain killer (analgesic) and fever depressant (antipyretic). However‚ because it is a relatively strong acid‚ salicylic acid has the undesirable side effect
