    Acetic acid / ə ˈ s iː t ɪ k /, systematically named ethanoic acid / ˌ ɛ θ ə ˈ n oʊ ɪ k /, is an acidic, colourless liquid and organic compound with the chemical formula CH 3 COOH (also written as CH 3 CO 2 H, C 2 H 4 O 2, or HC 2 H 3 O 2). Vinegar is at least 4% acetic acid by volume, making acetic acid the main component of vinegar ...

    A third example is illustrated by the chemical reaction of dissociation of a weak acid HA (such as acetic acid, A = CH 3 COO −): HA ⇌ H + + A −. Vinegar contains acetic acid. When acid molecules dissociate, the concentration of the undissociated acid molecules (HA) decreases and the concentrations of the product ions (H + and A −) increase.

    The acetic acid, together with the malic acid naturally present in apple juice, contribute to the sour taste of this vinegar. [ 3 ] There is no high-quality clinical evidence that regular consumption of apple cider vinegar helps to maintain or lose body weight , [ 5 ] or is effective to manage blood glucose and lipid levels.

    The term "spirit vinegar" is sometimes reserved for the stronger variety (5% to 24% [36] acetic acid) made from sugar cane or chemically produced acetic acid. [37] To be called "spirit vinegar", the product must come from an agricultural source and must be made by "double fermentation". The first fermentation is sugar to alcohol, and the second ...

    Next, thrust in an inward and upward motion on the diaphragm. This will force air out of the lungs and remove the blockage. Repeat these abdominal thrusts up to five times, the doctor advised.

  9. Titration - Wikipedia

    en.wikipedia.org/wiki/Titration

    If one reagent is a weak acid or base and the other is a strong acid or base, the titration curve is irregular and the pH shifts less with small additions of titrant near the equivalence point. For example, the titration curve for the titration between oxalic acid (a weak acid) and sodium hydroxide (a strong base) is
