a lot it should be better. Variables: Independent Variables: • Amount of antacid • Concentration of acid • State of antacid Dependent Variables: • Amount of acid added/dropped to neutralize the antacid Controlled: • Titration technique • Indicator type • Concentration of acid • State of antacid Materials: 1. Safety goggles 2.

Purpose: The purpose of this lab was to determine how to use an indicator in a titration process, in addition to using indicators to determine pH. Materials: DI water Buret Stand Clamp 150ml beaker Waste beaker Vitamin c tablet Vitamin c solution Phenolphthalein Acetic acid solution Ammonium hydroxide solution Ammonium chloride solution Sodium acetate solution Sodium carbonate solution Glass stirring rod Well plate Mortar and pestle Erlenmeyer flask Weighing pan Procedure: Vitamin C Titration

titrating the mixture with 0.1 M HCl to a bromocresol green end point. After 2L of 0.1M HCl were prepared, and divided among all groups. 25.00-mL aliquot of unknown solution was pipetted into a 150mL volumetric flask, using bromocresol green as the indicator, to observe the color change from a tinted light blue to a tinted light green, being the

Determinants Leading Indicators, on the other hand, focus on non-financial indicators including quality of service, flexibility resource utilization and innovation. According, to Fitzgerald (1991) comprehensive approach to performance tracking outlined in the results and determinants framework is suitable

reducing agent called Sodium thioglycolate was added, removing the free oxygen by chemically binding with it. Thioglycolate broth, also called a reducing medium, eradicates the tube of oxygen. Rasazarin is a pink dye that indicates oxygen depletion an indicator for oxygen depletion. The test results determine oxygen requirements the organism requires. 1. Strict aerobes need oxygen to grow. Growth will only appear at the top of the tube. 2. Strict anaerobes require the complete absence of oxygen. Growth

Impact of Globalization The implications of globalization for a national economy are many. Globalization has intensified interdependence and competition between economies in the world market. These economic reforms have yielded the following significant benefits; Globalization in India had a favorable impact on the overall growth rate of the economy. This is major improvement give that India’s growth rate in the 1970 s was very low at 3% and GDP growth in countries like Brazil, Indonesia, Korea

In this experiment, the group was given two unknown solutions and were told to discover the pH of each solution and if the two unknown solutions could be neutralized. The question they were solving for was; “How do you determine whether two solutions are acids or bases and whether these two solutions will neutralize each other and change their pH level?” The hypothesis the group decided on was; “We predict that if the unknown solutions are acids they will turn the blue litmus paper red and if they

Spectrophotometric determination of Ascorbic acid Concentration in an Unknown Solution Introduction: The naturally occurring organic compound with antioxidant properties is Ascorbic acid shortly referred as (AA). Normally the color of Ascorbic acid is white, but in some cases of impure samples it appears yellow in color. Ascorbic acid is solid in state. In water it dissolves well to give mildly acidic solutions. Ascorbic acid is one form ("vitamer") of vitamin C [1]. So, Ascorbic Acid (AA)

compound is to be investigated and identified. The lab group takes this goal a step further and also compares it against products found around the member’s homes. Multiple titrations will be performed, both with use of the PASCO program and by manual indicator. Through these experiments, different calculations will be performed to help in the analysis. In addition, a dilution study is performed to see the effects of dilution against an acid or base. The procedures used to identify the unknown compound

In the ADI Molarity Lab, the primary tasks was to use different values of moles of solute, volume of solvent, and molarity to find the mathematical relationships between them. To find these relationships, our group had to change the quantities of each of the variables and visually observe the molarity within the solution. For instance when using Cobalt (II) Nitrate to find the relationship between volume of the solution and the molarity of the solution; the group kept the amount of moles of the
