Experiment No. ___________________ Date ___________________ NEUTRALIZATION TITRATIONS INTRODUCTION The neutralization of hydronium or hydroxide ion to form water is widely used as the basis for volumetric determinations of acids‚ bases and salts of weak acids. The reaction is characterized by a rapid change in pH near the equivalence point‚ a change that is readily detected by an acid-base indicator or that can be followed electrically by use of a pH meter. Neutralization titrations

be cleaned thoroughly with tap water. While cleaning the buret‚ it is also checked to make sure there are no leaks. The ring stand is then set up with a buret clamp and the cleaned buret placed in it. Then the buret is filled with 5-10mL of sodium hydroxide‚ M .0466 NaOH‚ three times and emptied after each time to completely rinse the buret. The buret is now filled will NaOH until it reads at the 0.00mL mark on the buret. The initial volume of NaOH in the buret is then recorded into lab books

acid‚ is simply not enough. Next‚ a series of titration experiments had to be done. In the first series‚ a titration is completed of sodium hydroxide (NaOH) with KHP. Three reps were completed and the resulting data led to the finding of the molarity of the sodium hydroxide. The second part of the titration series involved titrating the same prepared sodium hydroxide solution with Hydrochloric Acid (HCL). This is how the molarity of the HCL was determined. The last part to the titration series

The Equilibrium Constant of an Ester Hydrolysis Reaction Julia Stanley CHM 152 LL Dr. Asmita Kane Budruk Goal of the lab: The purpose of this laboratory is to determine the equilibrium constant‚ Kc‚ for the acid-catalyzed reaction between an unknown ester and water to produce an unknown alcohol and an unknown carboxylic acid. I was using Unknown Ester #3 with a density of 0.9342 and Molar Mass of 74.08 g/mol; alcohol with density 0.7914 and Molar Mass 32.04 g/mol. Chemical

BIOLOGY LAB REPORT PRACTICAL M1 TESTING FOR MACROMOLECULES Title : Testing for Macromolecules Abstract : To test for macromolecules (carbohydrates‚ lipids‚ nucleic acids‚ and proteins)‚ iodine solution‚ alcohol‚ aceto-orcein stain and copper sulfate solution are used. The conclusions for all of the tests are positive. Introduction: A) Carbohydrate (starch) Carbohydrates are chemical compounds that contain oxygen‚ hydrogen‚ and carbon atoms. They consist of monosaccharide

Procedure: 1. Each group will cut three agar cubes: A 3cm cube‚ a 2cm cube‚ and a 1cm cube. CUT AS ACCURATELY AS POSSIBLE. (This may be already completed for you.) 2. Pour 200mL of 0.1M sodium hydroxide solution into your 400mL beaker. 3. Immerse your 3 cubes in the sodium hydroxide solution‚ noting the time. 4. Let the cubes soak for approximately 10 minutes. 5. Periodically‚ gently stir the solution‚ or turn the cubes over. 6. After 10 minutes‚ use a spoon or tongs

Taking 20ml of stock solution in a flask & then added 10ml of NH4OH.Then a white gelatinous ppt is formed which indicates the presence of Aluminum. Al3+ +NH4OH→Al(OH)3↓+ +NH4 Taken 20ml of stock solution ina flask & then add 10ml of sodium hydroxide solution slowly‚ a white gelatinous ppt is formed. Al3+ +NaOH → Al(OH)3↓+Na+ Then more NaOH is added to dissolve the ppt. Al(OH)3+NaOH→NaAlO2+H2O After sometimes added AlCl3 & Cobalt nitrate‚ then a blue ppt observed.
