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 colors depending on its pH level was

pH pH means Power of Hydrogen or Potential of Hydrogen. pH is a scale of acidity from 0 to 14. It tells how acidic or alkaline a substance is. More acidic solutions have lower pH. More alkaline solutions have higher pH. Substances which are not acidic or alkaline i.e neutral usually have a pH of around 7. Acids have a pH less than 7. Alkalis have a pH greater than 7. There are a lot of ways for finding the pH of something. One way is to use litmus paper. The pH paper is able to tell how strong

Lab Report: Purpose: The Objective of this lab was to learn how to measure the pH (or acidity) of commonly known fluids‚ using the correct tools and procedures. To then use that data to document the changes noticed when mixing those same fluids and changing their respective pH levels. Materials: In order to conduct this experiment several pieces of equipment and other materials were needed. The first item was a graduated cylinder‚ which was used in order to measure out the precise

Question 1 Critique Dr. Honeydew’s report. Specifically‚ discuss what is missing and how the missing information should have been presented. First the PH measurements‚ Dr. honey dew does not explain how the PH device was calibrated or if the blood sample was added or mixed with anything prior to the measuring of the pH (like water‚ etc.). In regards to the absorption spectroscopy‚ the method by which the concentration was obtained is questionable. Was the concentration known before the experiment

Performance Indicator Memo Executive Summary The aim of Performance Indicator is to increase golf ball manufacturers’ value by increasing revenue from new ball sales as a result of eliminating older‚ used balls through its color change coating technology. Although there appears to be a possible financial benefit based on the future perceived demand for new golf balls‚ PI’s new technology does not appear to have any transparent benefit or value creation for the end consumer (golfer). Consequently

An economic indicator is a statistic that indicates the current status of the economy‚ and how the economy will likely perform in the future. Investors and other private or government organizations use this information as a tool to make business decisions. By gathering historical data about the economy and comparing it to current trends‚ you can compile a snapshot of economic fluctuations. The direction of an indicator may vary according to changes in the economy. The indicator can be leading‚

BY: SH The Market Potential Index is used to compare countries that are in transition and entering the markets. This allows companies to determine if a country has the capacity to market a product successfully. Michigan State University Center for International Business Education and Research implements the study on a yearly basis in order to compare and rank the countries on market potential through eight different dimensions with a scale that ranges from one to one-hundred. It is important to

Attitude Indicator (Artificial Horizon) The Attitude Indicator shows rotation about both the longitudinal axis to indicate the degree of bank‚ and about the lateral axis to indicate pitch (nose up‚ level or nose down). It utilizes the rigidity characteristic of the gyro. It is gimballed to permit rotation about the lateral axis indicating pitch attitude‚ and about the longitudinal axis to indicate roll attitude. Once powered up‚ the indicator is maintain in a fixed position no matter what
