Aspirin. charge that attracts to the positively charged hydrogen. A more stable structure is formed when the charge on the oxygen moves from being a lone pair to forming a double bond and the ether substituents are removed. In the presence of Hydronium‚ the negatively charged oxygen shares electrons with a hydrogen from the reagents. This mechanism allows for the formation of Salicylic Acid. When Acetic Anhydride is used as a reagent‚ the double bond on the ketone is transferred as a charge to the

Chapter 1 The Chemical World Chemistry a science that studies matter – its properties and changes. Matter is anything that has mass and takes up space. Matter is made up of atoms and molecules. Scientific Method Observation of nature → Hypothesis (possible explanation) → Experiments to confirm or revise hypothesis Many observations lead to scientific law – a statement of the relationship between different parts of nature. Ex: law of conservation of mass- “ matter is neither created or destroyed”

have a neutral charge. Neutrons are also one amu like protons. Neutrons can move from the nucleus of an atom making an atom an isotope. The neutron symbol is . Electrons are located outside the nucleus in energy levels. Electrons have a negative charge and weigh approximately 1/2000th of an amu. The weight is almost insignificant. Electrons can vary in an atom making cations and anions. Cations are a positive charge when an atom loses an electron. Anions are a negative charge when an atom gains

Abstract In this experiment‚ the Ksp for calcium sulfate dihydrate‚ CaSO4·2H2O‚ by titrating 4 times a calcium sulfate dihydrate solution with diprotic EDTA‚ H2(EDTA)2-. For each trial we found the Ksp by means of molarities and activities. The results for the Ksp using only molarities was very different than the Ksp using activities. The average Ksp using molarity only was 2.26 x 10-4 and the average Ksp using activity turned out to be 2.31 x 10-5. The actual Ksp however‚ is 3.14 x 10-5. A percent
