ACID BASE TITRATION OBJECTIVES 1. To demonstrate the basic laboratory technique of titration 2. To learn to calculate molarity based on titrations INTRODUCTION Molarity (M) or molar concentration is a common unit for expressing the concentration of solutions. It is defined as the number of moles of solute per liter of solution (or millimoles of solute per milliliter of solution). The concentration of a basic solution can be determined by titrating it with a volume of a standard acid solution (of

Experimental Part 1: Reaction First the glassware apparatus for the reaction was set up. 3.861-grams of isoborneol‚ 2.21-mL of glacial acetic acid‚ and 4.39-mL of 6% NaOCl solution were mixed in a 125-mL Erlenmeyer flask. Another 35-mL of 6% NaOCl solution was added to a separatory funnel and supported over the flask. The NaOCl in the sep funnel was slowly added into the Erlenmeyer flask with vigorous swirling‚ approximately 2-mL every 30 seconds until all the NaOCl from the sep funnel had been

concentration of acetic acid in a sample of vinegar? Prediction: The manufacture of claims on the label that the vinegar contains 5.0% acetic acid‚ which translates into a 0.87 mol/L concentration of acetic acid. The concentration of acetic acid in the vinegar sample should be the same. Purpose: If we add acid solution to basic solution to produce water and salt this activity is called titration. It involves carefully adding one solution to another until chemically equivalent amounts react. Vinegar is a

Zinc Reacts with Vinegar’s Acetic Acid To Produce Electricity March 7‚ 2014 Abstract This research is about the chemical reaction of zinc with acetic acid to produce a short amount of electricity. Even though it only conducts a small amount of voltage‚ we investigated and experimented on how it can produce more than usual without adding any other components on the project except zinc‚ copper‚ vinegar‚ or a unique container that can increase the voltage of our product. The zinc can produce

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

Decreased pH in the blood is generally known as acidosis. The body cells continuously respire and release carbon dioxide. The lungs may fail to efficiently expel the CO2. This condition is known as alveolar
