Physical properties. 24 + 4 + 32 = 60 g/mol C2H4O2 Acetic acid, also known as ethanoic acid, is an organic chemical compound best recognized for giving vinegar its sour taste and pungent smell. This is done in two simplified stages. Acetic acid has a distinctive sour taste and pungent smell. Acetic acid is an organic compound with the formula CH 3 COOH. Acetic acid is a colourless liquid; with a strong vinegar-like odour. The other molecular formula mentioned in the quote, HC2H3O2 does try to emphasize that there is one acidic hydrogen and 3 non-acidic hydrogens on the molecule (CH3COOH does that better.) The systematic IUPAC name of acetic acid is ethanoic acid and its chemical formula can also be written as C 2 H 4 O 2. Synonym: (4-Methoxybenzothioylthio)ethanoic acid, 2-[(4-Methoxyphenylthioxomethyl)thio]ethanoic acid, CTA, RAFT dithiobenzoate Empirical Formula (Hill Notation): C 10 H 10 O 3 S 2 Molecular Weight: 242.31 Now add up the mass totals for each element to get the total mass of the acid. Synonyms: Ethanoic acid, vinegar, ethylic acid, vinegar acid, methanecarboxylic acid, TCLP extraction fluid 2, shotgun, glacial acetic acid, glacial ethanoic acid. Since it has a carbon atom in its chemical formula, it is an organic compound. C2H4O2 is very much like the molecular formula for a carbohydrate, i.e., C2(H2O)2. Acetic acid also called ethanoic acid having the molecular formula CH 3 COOH prepared industrially by various methods and uses commonly as a solvent and in the preparation of organic chemicals like acetate, acetone, acetic anhydride, acetaldehyde alcohol, vinegar, etc. The most common method is oxidising primary alcohols. Acetic acid which is also known as Ethanoic acid is a colorless organic acid with chemicals formula C 2 H 4 O 2 is liquid with strong and distinctive pungent and sour smell. Pure water-free acetic acid (glacial acetic acid) is a colorless hygroscopic liquid and freezes below 16.7 °C (62 °F) to a colourless crystalline solid. 2 O : 2 x 16 = 32. Acetic acid (also known as methanecarboxylic acid and ethanoic acid) is a colourless liquid, which has a strong and pungent smell. About Acetic acid. Acetic acid: It is a mild organic acic with molecular formula CH3COOH and IUPAC name Ethanoic acid when pure it is as clear as pure water and freezes below the room temperaure. Acetic acid is a main component of vinegar and gives vinegar its characteristic smell. Molecular formula: C 2 H 4 O 2. Acetic Acid Properties and Formula. 2 C : 12 x 2 = 24. Acetic acid got its name from a word “Acetum”, which is a Latin word for vinegar. Substance name: Acetic acid. 4 H : 1 x 4 = 4. Ethanoic acid is the most common example of a carboxylic acid. CASR number: 64-19-7. It is a carboxylic acid consisting of a methyl group that is attached to a carboxyl functional group. Acetic acid is an acid and the formula CH3COOH emphasizes that fact. This acid is also known as Acetic acid ( C2H4O2 ) To find the formula mass (total mass) of the acid, take each of the elements out separately and add their mass together. Making Ethanoic Acid. These acids are a series of organic compounds that contain a carboxyl group (COOH), and there are a variety of methods that are used to produce them. Synonyms: Ethanoic acid, Vinegar, Hydrogen acetate, Methanecarboxylic acid CAS: 64-19-7 Acetic acid is a colourless liquid organic compound.
