C_2H_5OH, C_2H_5C0_2CH3 and H_20 at equilibrium, and then answer the following questions. What is the rate of the forward reaction before any HCH3C02 has been added to the flask? Greater than zero, but less than the rate of the reverse reaction.
Aceticacid is produced and excreted by aceticacid bacteria, notably the genus Acetobacter and Clostridium acetobutylicum.
When aceticacid is added to water, due to electronegativity differences of oxygen and hydrogen in —OH group of aceticacid and dipole interaction with water molecule, the aceticacid is transformed into acetate ion and H+ ion which furthur combines with watertoform hydronium ion.
