Acidulants. The other component of any system of chemical leavening based on sodium hydrogen carbonate is an acid. The original acidulants were sour milk (lactic acid), vinegar (acetic acid), lemon juice (citric acid) and cream of tartar (potassium acid tartrate). All of these will react immediately on mixing so that the carbon dioxide is released straight away. The product had to be baked before the carbon dioxide escaped from the batter or product. The only delay possible was that allowed by the batter viscosity. 

A solution of vinegar (acetic acid) is titrated with lye (sodium hydroxide) HC2H3O2 + OH - H20 + C2 H302 ... 

The acid signature is just a bit more complicated. Its a double-bonded oxygen plus a hydroxyl (-OH) group, both attached to the same carbon. The main ingredient in vinegar, acetic acid, is an example. 

You find them in citrus fruits (citric acid), vinegar (acetic acid), aspirin (acetylsalicylic acid), and numerous other natural and synthetic compounds, as well on numerous organic exams. In this chapter you explore the structure, synthesis, and reactions of these acids and acids like them. 

Vinegar and Pyroligneous Acid. Vinegar (acetic acid) is mentioned several times in the Bible, as, for example, in Proverbs 10, 26 As vinegar to tire teeth and as smoke to the eyes, so is the sluggard to them that send him. It was known to Theophrastus three centuries before the birth of Christ, and was used in tire manufacture of white lead and verdigris and in extracting mercury from cinnabar (I). 

The reactions in Table 13.8 show that carbon dioxide is a common product in many neutralization reactions. This is clearly displayed when a drop of vinegar (acetic acid) is added to baking soda (sodium bicarbonate). Some aspirin includes an antacid in their formulation to neutralize some of the acidity imparted by the aspirin (acetylsalicylic acid). These are commonly referred to as buffered aspirins. 

Vinegar, acetic acid, has been mentioned as a home remedy, an... 

A simple way to remove boiler scale from the inside of a kettle or a coffee maker is to add vinegar. Acetic acid in vinegar reacts with calcium (and magnesium) carbonates to form soluble salts. (Remember that all acetates are soluble.)... 

Many cleaning products contain an acid or a base. For example, some window cleaners contain vinegar (acetic acid). Other window cleaners contain ammonia (a base). Oven cleaners, however, contain only bases. This activity will help you infer why. 

Some experts believe that hydrogen forms more compounds than any other element. These compounds include water, sucrose (table sugar), alcohols, vinegar (acetic acid), household lye (sodium hydroxide), drugs, fibers, dyes, plastics, and fuels.

A 10.00-mL sample of vinegar (acetic acid, CH3COOH) was pipetted into a flask, two drops of phenolphthalein indicator were added, and the acid was titrated with 0.1008 M NaOH. 

WARNING Vinegar (acetic acid) may cause skin and eye irritation. 

For larger scales, shallow trays made of corrosion-resistant metal or plastic placed in portable trolleys may be used for efficient liquid-air contact. The trolleys are placed in a sterile room with frequent sterile air changes under closely controlled temperature and humidity conditions. Efficient air-liquid contact may also be obtained from a loosely packed, moist, solid medium permeated with air. For instance bran is used as the substrate for enzyme production by Aspergillus oryzal. Wine vinegar (acetic acid) is produced by trickling wine (basically ethanol in water) over a short tower of wood chips, which are used both as a support and to provide air to Acetobacter aceti [13] (Eq. 16.15). By law, the acetic acid (3-5% in water) in vinegar must be produced by fermentation, and not by petrochemical methods. 

Home-made mayonnaise has been implicated in various incidences of food poisoning (Weagant, Bryant, and Bark, 1994 Erickson et al., 1995 Al-Ahmadi, El Bushra, and Al-Zahrani, 1998). The use of vinegar (acetic acid) as an acidulant, at pH 3.6-4.0 has been suggested for prevention of contamination with pathogens, particularly Salmonella. 

You may see concentration described in common terms out in the real world. For example, you might see a bottle of vinegar that say s 5 % on it. That means that out of 100% of the solution, 5% is actually vinegar (acetic acid). Other percentages are given by mass. The concentrated hydrochloric acid that you use in the lab is purchased in bottles that are 37% HCl. That means that for...
