If acetic acid is the only acid that vinegar contains , calculate the concentration of acetic acid in the vinegar. if the pH of vinegar is 2.7

  • Chemistry - ,

    pH = -log(H^+)
    2.7 = -log(H^+).
    (H^+) = 0.002
    .........CH3COOH ==> H^+ + CH3COO^-
    ...........x.........0.002..0.002

    Ka = (H^+)(CH3COO^-)/(CH3COOH)
    Substitute 0.002 for H^+ and CH3COO^-, and x0.002 for CH3COOH, look up Ka, solve for x which = (CH3COOH)

  • Chemistry - ,
