WebSynthesis of Aspirin/Acetylsalicylic acid (C 9 H 8 O 4). Step 1: Dry an Erlenmeyer flask and add 3 grams of salicylic acid to it. Step 2: Put 5 to 8 drops of 85% phosphoric acid along with 6 mL of acetic anhydride into the flask. Step 3: Mix the solution and keep the flask in warm water for 15 minutes. Step 4: To the warm solution, add 20 drops of cold water dropwise. WebBlocking antibody may impair binding of acetylcholine to the receptor, leading to poor muscle contraction. Modulating antibody causes receptor endocytosis resulting in loss of AChR expression, which correlates most closely with clinical severity of disease. Approximately 10-15% of individuals with confirmed myasthenia gravis have no … WebIn this experiment, constitutive titration of NaOH determine the pKa of acetic acid. The pKa value was analysed and identified in this experiment by looking at the half equivalence point of titration curves. For acetic acid, the pKa value is determined to be 5. while for citric acid, the pKa values are determined to be 3, 4 and 5. canal 5 spanish windows download
