Acetic Acid Copper Balanced Equation
What is Acetic Acid?
Acerb acid is an organic chemical compound with the formula CHiiiCOOH. It is a carboxylic acid consisting of a methyl group that is attached to a carboxyl functional group. The systematic IUPAC name of acetic acid is ethanoic acrid and its chemic formula tin also be written every bit C2H4O2. Vinegar is a solution of acetic acid in water and contains between 5% to xx% ethanoic acid past volume. The pungent smell and the sour taste is characteristic of the acetic acid nowadays in it.
An undiluted solution of acetic acid is commonly referred to as glacial acetic acid. Information technology forms crystals which announced like ice at temperatures below 16.6oC. It has a broad range of applications as a polar, protic solvent. In the field of analytical chemistry, glacial acetic acrid is widely used in order to estimate substances that are weakly alkaline metal.

Structure of Acetic acid- CH3COOH
- It tin be observed in the solid-state of acetic acrid that there is a chain of molecules wherein individual molecules are connected to each other via hydrogen bonds.
- Dimers of ethanoic acid in its vapour phase tin can exist found at temperatures approximating to 120o
- Even in the liquid phase of ethanoic acid, its dimers can be establish when information technology is present in a dilute solution. These dimers are adversely affected by solvents that promote hydrogen bonding.
- The structure of acetic acid is given by CH3(C=O)OH, or CHiiiCOiiH
The structure of acetic acrid is illustrated beneath.
Structurally, ethanoic acrid is the second simplest carboxylic acid (the simplest existence formic acid, HCOOH), and is essentially a methyl group with a carboxyl functional grouping attached to it.
Properties of Acetic acrid- CH3COOH
| CH 3 COOH | Acetic Acrid |
| Molecular weight/tooth mass of CH iii COOH | 60.052 one thousand/mol |
| Density of Acetamide | 1.05 grand/cm³ |
| Boiling Betoken of Acetamide | 118 °C |
| Melting Betoken of Acetamide | xvi.6 °C |
Preparation of Acerb acid- CH3COOH
Acetic acrid is produced industrially via the carbonylation of methanol. The chemic equations for the three steps involved in this process are provided beneath.
- CH3OH (methanol) + HI (hydrogen iodide) → CH3I (methyl iodide intermediate) + H2O
- CHiiiI + CO (carbon monoxide) → CHthreeCOI (acetyl iodide)
- CH3COI + H2O → CH3COOH (acetic acid) + Hullo
Here, a methyl iodide intermediate is generated from the reaction between methanol and hydrogen iodide. This intermediate is so reacted with carbon monoxide and the resulting compound is treated with h2o to afford the acetic acid product. Information technology is of import to notation that a metal carbonyl circuitous must exist used as a goad for pace two of this process.
Other Methods of Preparing Acetic Acrid
Some naphthalene salts of cobalt, chromium, and manganese can exist employed equally metallic catalysts in the oxidation of acetaldehyde. The chemical equation for this reaction tin be written as:
Otwo + 2CH3 CHO → 2CHiiiCOOH
Ethylene (C2Hiv) tin can exist oxidized into acetic acrid with the aid of a palladium goad and a heteropoly acid, every bit described by the following chemical reaction.
O2 + C2Hfour → CH3COOH
Some anaerobic bacteria accept the ability to directly convert sugar into acetic acid.
Chalf-dozenH12Ohalf-dozen → 3CH3COOH
It can be noted that no ethanol intermediates are formed in the anaerobic fermentation of sugar past these leaner.
Physical Properties of Acerb Acid
Even though ethanoic acid is considered to be a weak acrid, in its concentrated form, information technology possesses stiff corrosive powers and can even attack the human being skin if exposed to it. Some general properties of acetic acid are listed below.
- Ethanoic acid appears to be a colourless liquid and has a pungent odour.
- At STP, the melting and boiling points of ethanoic acid are 289K and 391K respectively.
- The molar mass of acetic acrid is lx.052 grand/mol and its density in the liquid course is 1.049 thousand.cm-iii.
- The carboxyl functional group in ethanoic acid tin crusade ionization of the chemical compound, given by the reaction: CHiii COOH ⇌ CH3COO– + H+
- The release of the proton, described by the equilibrium reaction above, is the root cause of the acidic quality of acerb acrid.
- The acid dissociation abiding (pKa) of ethanoic acid in a solution of water is 4.76.
- The conjugate base of acetic acid is acetate, given past CH3COO–.
- The pH of an ethanoic acid solution of ane.0M concentration is 2.four, which implies that it does not dissociate completely.
- In its liquid grade, acetic acid is a polar, protic solvent, with a dielectric constant of vi.2.
The metabolism of carbohydrates and fats in many animals is centered around the bounden of acerb acrid to coenzyme A. Generally, this chemical compound is produced via the reaction between methanol and carbon monoxide (carbonylation of methanol).
Chemic Properties of Acerb Acid
The chemical reactions undergone by acetic acid are like to those of other carboxylic acids. When heated to temperatures above 440oC, this chemical compound undergoes decomposition to yield either methane and carbon dioxide or water and ethenone, as described past the following chemic equations.
CHthree COOH + Rut → CO2 + CHiv
CH3 COOH + Oestrus → H2C=C=O + H2O
Some metals such as magnesium, zinc, and atomic number 26 undergo corrosion when exposed to acetic acrid. These reactions upshot in the germination of acetate salts.
2CH3 COOH + Mg → Mg(CH3COO)2 (magnesium acetate) + H2
The reaction between ethanoic acrid and magnesium results in the formation of magnesium acetate and hydrogen gas, equally described by the chemical equation provided in a higher place.
Other Reactions
Acerb acid reacts with alkalis and forms acetate salts, as described below.
CHthree COOH + KOH → CHiiiCook + H2O
This chemical compound too forms acetate salts by reacting with carbonates (along with carbon dioxide and h2o). Examples of such reactions include:
2CH3COOH + NaiiCO3 (sodium carbonate) → 2CH3COONa + CO2 + HtwoO
CH3COOH + NaHCO3 (sodium bicarbonate) → CHthreeCOONa + CO2 + H2O
The reaction between PCl5 and ethanoic acid results in the formation of ethanoyl chloride.
Uses of Acetic Acid
Ethanoic acid is a very important organic compound in the twenty-four hour period-to-day lives of humans. Some of import uses of acetic acid are listed below.
- Acerb acid is used as an clarified due to its antibacterial qualities
- The manufacture of rayon cobweb involves the apply of ethanoic acid.

- Existence the major elective of vinegar, it finds apply in the pickling of many vegetables.
- The industry of rubber involves the utilize of ethanoic acid. It is also used in the manufacture of various perfumes.
- It is widely used in the product of VAM (vinyl acetate monomer).
- When two molecules of acetic acrid undergo a condensation reaction together, the product formed is acetic anhydride.
Acetic Acrid as a Solvent
In its liquid state, CH3COOH is a hydrophile (readily dissolves in water) and also a polar, protic solvent. A mixture of acerb acrid and water is, in this manner, similar to a mixture of ethanol and h2o. Acerb acid likewise forms miscible mixtures with hexane, chloroform, and several oils. Even so, it does not class miscible mixtures with long-chain alkanes (such as octane).
The desirable solvent properties of acerb acid, along with its ability to form miscible mixtures with both polar and non-polar compounds, brand it a very important industrial solvent. It is widely used in the industrial preparation of dimethyl terephthalate (DMT).

No, CH3COOH is a weak acrid. It undergoes complete dissociation but when it is reacted with a strong base. Hydrochloric acid is a much stronger acid than acetic acid.
How can acerb acid be prepared?
Information technology can be prepared by reacting methanol with hydrogen iodide and adding carbon monoxide to the product (methyl iodide) in gild to obtain acetyl iodide. Upon hydrolysis, acetyl iodide yields acetic acid.
Is acerb acid a vinegar ?
Vinegar is a solution of acerb acid in water and contains betwixt 5% to viii% ethanoic acid past volume.
Is acetic acrid harmful to humans ?
Exposure to more full-bodied solutions of acetic acid (>25%) can cause corrosive damage. Animate vapours with high levels of acerb acid can cause irritation of eyes, nose and throat, cough, chest tightness, headache, fever and confusion
