Acid-Base Titrations A Titration of Potassium Hydroxide Phthalate and Sodium Hydroxide Hanna Piper Department of Chemistry‚ SUNY College at Brockport‚ Brockport‚ NY 14420 Chemistry 205.06 Abstract Titrations are used to find the molarity of an unknown solution. A titration begins with an analyte and titrant being used to measure the unknown molarity of the analyte. In the following experiment‚ sodium hydroxide was used as the titrant and potassium hydroxide phthalate was used as the

purpose of a synthesis essay is to make insightful connections. Those connections can show the relationship(s) between parts of a work or even between two or more works. It is your job to explain why those relationships are important. In order to write a successful synthesis essay‚ you must gather research on your chosen topic‚ discover meaningful connections throughout your research‚ and develop a unique and interesting argument or perspective. A synthesis is not a summary. A synthesis is an opportunity

D Biology Procedure- see attached Data and Results- see attached Theory- PH stands for the power of hydrogen. People refer to the pH scale as a tool for finding out if a substance is acidic‚ basic‚ or neutral. This scale goes from zero to fourteen. The number seven is neutral. Any number higher than seven on this scale is basic. Any number lower is acidic

alcohol (1.0 mL) and excess glacial acetic acid(1.5 mL‚ 17.6M) were eppendorf pipetted into a 5 mL conical vile. This mixture was acid catalyzed by the addition on two drops of H2SO4. The mixture was then heated to 150-160⁰C in order to increase energy for esterification to occur over a period of 60- 75 minutes. The mixture then was cooled to room temperature before the addition of 5% aqueous sodium bicarbonate( 1.0 mL) in order to react excess acetic acid to form a the anionic form sodium acetate

sensory effect of esters. Isopentyl acetate is made from the direct esterification of acetic acid and isopentyl alcohol. The direct esterification of acetic acid and isopentyl alcohol is an equilibrium reaction that shifts the product to the side by using the excess of one of the starting reagents. Acetic acid usually used in excess because it is easier to remove from the reaction. The excess acetic acid and the remaining isopentyl alcohol are removed through extraction with water and sodium bicarbonate
