Theoretical ka of acetic acid
Acetic acid /əˈsiːtɪk/, systematically named ethanoic acid /ˌɛθəˈnoʊɪk/, is an acidic, colourless liquid and organic compound with the chemical formula CH3COOH (also written as CH3CO2H, C2H4O2, or HC2H3O2). Vinegar is at least 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water and other trace elements. Acetic acid is the second simplest carboxylic acid (after formic acid). It is an important chemical r… WebbThe Ka of acetic acid in a solution titrated with NaOH was calculated to be 2.88*10-5. In Part B the theoretical pH for H2PO4-and HPO4-2was calculated to be 8.71 and 11.3 respectively. These values resulted in a 24.2% error and a 1.5% error respectively.
