Chemistry: Acid-base Titration Essay -- essays research papers

Chemistry Acid-Base TitrationPurposeThe accusing of this experiment were a) to review the concept ofsimple acid-base reactions b) to review the stoichiometric calculations affect in chemical reactions c) to review the staple fibre laboratory procedure of atitration and introduce the student to the concept of a primary standard and the branch of standardization d) to review the calculations involving chemicalsolutions e) to help the student improve his/her lab technique.TheoryTitration was used to study acid-base electroneutralization reactionquantitatively. In acid-base titration experiment, a solution of accurately KHP assimilation was added gradually to another solution of NaOH concentrationuntil the chemical reaction between the two solutions were completed. Theequivalence efflorescence was the stay at which the acid was completely reacted with orneutralized by the base. The point was signaled by a changing of color of anindicator that had been added to the acid solution. forefinger was substance thathad distinctly different colors in acidic and basic media. Phenolphthalein was acommon indicator which was colorless in acidic and neutral solutions, butreddish pink was result in basic solutions. sound acid (contained H+ ion) andstrong base ( contained OH ) were 100% ionized in water and they were allstrong electrolytes. ProcedurePart A. Investigating unscathed NaOH for use as a possible primary standard jump o...
