Determining the Molarity of Acetic Acid in Vinegar Abstract This experiment was done to determine the molarity of acetic acid in vinegar. The acetic acid in vinegar was titrated with a strong base sodium hydroxide to determine the equivalence point of this chemical reaction. The indicator phenolphthalein was used because the moment it changes color is on the basic side of the pH scale. To insure the experiment was done with the most accuracy‚ the two conductors of this experiment took three

Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH‚ identify highly acidic household cleaning chemicals‚ and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First‚ to create 0.5L of 0.2M solution of NaOH‚ standard 3M NaOH solution was obtained. Next‚ calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and‚ as

That‚ plus the fact that all the starting and finishing materials are non hazardous and safe‚ is why this is one of the first chemical reactions that many people are exposed to The purpose of this experiment tests which of the two reactants (vinegar and baking soda) is the limited

Figure 2 show the wet crystal after the precipitated salt was being filtered by suction. The wet crystal was light purple in colour. Figure 3 show the end product after drying the wet crystal at 105°C in the drying cabinet (oven)

Acid-Base Balance and Fluids and Electrolytes Student’s Name Institutional Affiliation Date Due Respiratory Acidosis Respiratory acidosis refers to a medical defect in which hypoventilation occurs leading to increased concentration of carbon dioxide in the blood and decreased level of pH. 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

Abandoned Acid Mine Drainage at Shoup’s Run Introduction Acid mine drainage (AMD) is an industrial waste which is the result of the extraction process of the mineral coal from the ground. It causes widespread pollution in the streams above and below the coals fields. AMD is caused when water flows through sulfur-bearing materials forming acidic solutions. It is formed when pyrite (FeS2)‚ an iron sulfide‚ is exposed and then reacts with air (O2) and water (H2O) to form sulfuric acid. 2FeS2 (s)

Recommendations 21 References 22 Appendices 22 Abstract This experiment was performed in order to determine the molarity of a solution and the percent by mass of acetic acid‚ CH3COOH in vinegar. Acetic acid is monoprotic and belongs to the carboxyl family of organic compounds. The titration method is used to neutralize the acids by using the standardized sodium hydroxide solution. It reacts with bases which is sodium hydroxide‚ NaOH to form salt and water. The equivalence point of this neutralization
