본문 1. title : Analysis of Acids and Bases in Everyday Life 2. purpose : To find out the concentration of acid or base through neutralization 3. theory 1) Definition of the acid and the base Arrhenius Acid: Substance that ionizes in water and emits protons (H+) Base: Substance that ionizes in water and emits hydroxide (OH-) Br0nsted-Lowry Acid: Proton(H+) donor Base: Proton(H+) acceptor Lewis Acid: Non-bonding electron acceptor Base: Non-bonding electron donor 2) neutralization an acid and a base react to form a salt. Water is frequently, but not necessarily, produced as well. Neutralizations with Arrhenius acids and bases always produce water where acid-alkali reactions produce water and a metal salt. Neutralization reactions do not necessarily imply a resultant pH of 7. 1 The resultant pH will vary based on the respective strengths of the acid and base reactants. 3) titration a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte. Because volume measurements play a key role in titration, it is also known as volumetric analysis. A reagent, called the titrant or titrator 2 is prepared as a standard solution. A known concentration and volume of titrant reacts with a solution of analyte or titrand 3 to determine concentration. 4)equivalence point the point at which an added titrant is stoichiometrically equal to the number of moles of substance (known as analyte) present in the sample: the smallest amount of titrant that is sufficient to fully neutralize or react with the analyte. In some cases there are multiple equivalence points which are multiples of the first equivalent point, such as in the titration of a diprotic acid. A graph of the titration curve exhibits an inflection point at the equivalence pointwhere the graph is steepest. 1 A striking fact about equivalence is that in a reaction the equivalence of the reactants as well as products is conserved. 하고 싶은 말 좀 더 업그레이드하여 자료를 보완하여, 과제물을 꼼꼼하게 정성을 들어 작성했습니다. 위 자료 요약정리 잘되어 있으니 잘 참고하시어 학업에 나날이 발전이 있기를 기원합니다 ^^ 구입자 분의 앞날에 항상 무궁한 발전과 행복과 행운이 깃들기를 홧팅 키워드 포트, 반응, 염기, 중화, 중화반응, 실험레포트
