Experiment #6: Colorimetric Determination of pH Almira‚ Faerie Carleen Lucile L. Gallardo‚ Charlotte O. Group #6‚ Chemistry 18.1‚ MHEG1‚ Ma’am Arlou Angeles September 23‚ 2013 I. Abstract The acidity of the four unknown solutions were determined with the use of colorimetry using McIlvaine’s buffer solutions varying in proportion of its constituents (disodium phosphate and citric acid). These buffer solutions were subjected to the addition of corresponding pH indicators and the variation of

Acid Base Titration bre’ana March 1‚ 2013 Purpose: The purpose of this experiment is to determine the concentration of a solution of NaOH by titration with a standard solution of HCl. It was also the purpose to determine the concentration of a sample of white vinegar by titration with a standard solution of NaOH. Introduction: Using the method of titration is how the experiment gets to the conclusion of the concentration of a solution. When doing this experiment‚ measurement is very important

In Hajime Isayama’s Shingeki no Kyojin‚ Mikasa and Eren are both working as soldiers in the Survey Corps. They each have their reasons for joining the squad‚ and they each have unique strengths that aid them in battle. On the other hand‚ they also have their weaknesses. As members of the Survey Corps‚ It is important for them to minimize their flaws in order to contribute to the advancement of their team. When it comes to honor‚ Mikasa is more respected than Eren. Therefore‚ because Mikasa is more

D. F. Nachman Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy 9/11/2014 Introduction: A chemical reaction often indicated by a transfer of energy measured in heat. By measuring this heat transfer in a constant pressurized environment‚ the enthalpy of the reaction can be used to infer certain information about a specific reactions reactants and products. The transfer of heat from outside sources in would be described as an endothermic reaction. Contrary‚ when

Executive summary The Ford Ka cannot be marketed to a specific demographic segment‚ as defined by traditional variables such as income‚ age‚ or marital status. Willingness to purchase the Ka was for the most part not dependent on membership in these traditional segments. Alternatively‚ we propose Ford develop a campaign toward a certain segment defined by attitudinal and psychographic variables. We plan to target this segment with tailored advertising campaigns addressing their unique worldview‚

Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid‚ potassium acid phtalate (HKC8H4O4‚ abbreviated KHP). This will be accomplished using the titration
