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

demonstrates how the composer explores important issues Robert Caswell’s Australian screenplay Scales of Justice ‘The Job’ explores many issues‚ including corruption within the workplace‚ racism and the avoidance of crime throughout the text. He deals with these themes and issues through the eyes of a naïve new Probationary Constable‚ Len Webber‚ as he battles with his conscience against right and wrong. In scales of Justice ‘The Job’‚ Constable Len Webber is new to the police Force. Sergeant O’Rourke

II: Titration with a pH Meter 1. Fill the 50-milliliter buret with a 0.25 molar NaOH solution. 2. Record volume. 3. Measure out between 20 milliliters and 40 milliliters of the unknown HCl solution. This amount must be different than the amount used in part I. 4. Record volume. 5. The amount of unknown HCl is then added to the 100-milliliter Erlenmeyer flask. 6. Insert the pH meter into the Erlenmeyer flask and record the initial pH of the acid. Remember to record the pH of the solution after

Scales of Justice shows a police force where there is a culture of corruption. The parts of the TV program that we saw were made up of two parts‚ The Job‚ and the Game. The Job is about a new probationary officer named Webber‚ and how he is forced to accept the corruption that occurs in the force‚ and ends up getting fired. The Game takes corruption to a new level involving higher powers such as MP’s and non-uniformed officers. They both are good examples of how it is a culture for them. The

I expect the Sensodyne toothpaste to be a neutral pH level as the manufactures claim that this products pH level is neutral

Consulting Chemists Institute Introduction The Consulting Chemists Institute was contracted by a local food manufacturer to determine if sodium benzoate‚ a common food preservative‚ undergoes significant chemical changes at the pH level encountered in the acidic environment of the stomach. Experimental Method Sodium benzoate was prepared by addition of an equimolar amount of aqueous sodium hydroxide (3 M‚ ~ 20 ml) to a benzoic acid (1.256 g‚ 10.3 mmol) /water mixture (10 ml). Benzoic

Nonbiological Material on the Reaction to a Changing pH Level This experiment was conducted to learn exactly how biological material responds to rising or dropping pH levels in comparison to how nonbiological material does. The dependent variable in this experiment was how the different materials react‚ and the independent variable was the type of material‚ biological or nonbiological. Tap water was the selected nonbiological material‚ and the generally known pH level for water is 7‚ or neutral

can reach a new pH level by interacting with soil. If water has a pH that is too high or too low‚ it can be life threatening to aquatic species and can corrode metal structures. After finding this out‚ I decided to test if water could reach an extreme pH just by interacting with soil around it. The question for this experiment therefore became the following. Will interaction with soil change the pH of water? I hypothesized that if water interacts with soil for three days‚ then the pH of the water will
