Kahakachchi, Uden and Tyson (2004) investigated the ability of various liquids to extract As(III), As(V), DMA(V), and MMA(V) from spiked soils. The extractants included deionized water, a citrate buffer, an ammonium dihydrogen phosphate buffer, 1M phosphoric acid, 5 % acetic acid, household vinegar, 0.1 M NaOH, and even Coca Cola . After eight days, the highest extractions for As(III), MMA(V), and As(V) were achieved with NaOH at 46, 100, and 84%, respectively. A 10 mM citrate buffer was most effective with DMA(V) with about 85 % removal after eight days. 

We frequently encounter acids and bases in our daily life. Fruits, such as oranges, apples, etc., contain acids. Household ammonia, a cleaning agent, and Liquid Plumber are bases. Acids are compounds that can donate a proton (hydrogen ion). Bases are compounds that can accept a proton. This classification system was proposed simultaneously by Johannes Brensted and Thomas Lowry in 1923, and it is known as the Brensted-Lowry theory. Thus any proton donor is an acid, and a proton acceptor is a base. 

Did you know that many of the chemical products in your home are hazardous, too For example, common household bleach, when used as directed, is safe for disinfecting and whitening clothing. Hazard labels on bleaching products, however, warn against mixing bleach with acids, household ammonia, or products that contain these chemicals. Bleach, when combined with acids, produces toxic chlorine gas. The products of combining bleach with ammonia are explosive. 

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. 

Phenomena. In the first step, one could clearly look at aggressive effects - the well-known phenomena of acidic and basic solutions. Concerning acids, one can demonstrate the spectacular reaction of concentrated sulfuric acid with sugar (see E7.1) or that of the behavior of acidic solutions with metals (see E7.2). One should discuss, in both cases, the statement that an acid is something which eats material away [5], and can demonstrate that other substances are produced by those acid reactions sulfuric acid and sugar produce black carbon and steam metals react to produce hydrogen and a salt solution, from which solid white salts may be obtained by the evaporation of water. In addition, acidic household cleaners like those that remove lime deposits could be introduced one could demonstrates that when lime deposit is removed by a cleaner solution, salt solution and carbon dioxide gas are produced (see E7.3). 

E7.3 Limestone Deposit Removers - Acidic Household Cleaners... 

Material Beakers, test tubes calcium carbonate powder, dilute hydrochloric acid, household limestone deposit remover, candle. 

Procedure Place a little amount of calcium carbonate powder in the beaker and cover with a few ml of hydrochloric add. After a short while, insert a burning candle into the beaker. After reaction is over, evaporate the remaining solution. Repeat the reaction with limestone deposit removers (acidic household cleaners) check the type of acid from its label and interpret the information. 

Nicknames added to the confusion. For example, baking soda used to make breads rise is actually sodium bicarbonate, but most people don t call it that. Battery acid, the liquid that allows electricity to be mysteriously generated in cars, is really sulfuric acid. Household laundry bleach is usually known as sodium hypochlorite by chemists. Or do you know anyone who says, Please pass the sodium chloride, at a meal ... 

Uses Foam stabilizer, vise, modifier in mild, neutral liq. detergents, shampoos, body wash, bubble baths, etc. mild synergist in neutral to acidic household, cosmetic, and personal care applies. 

One-step clean-and-shine products have become popular in the household market. These products are appHed to the floor with a sponge mop and their detergent action removes and suspends soil, which coUects on the mop and is removed when the mop is rinsed with water. The formulation, which remains on the floor, dries to a poHsh film. An earlier product of this type was dispensed from an aerosol as a foam. Formulas as of this writing (ca 1995) are appHed as Hquids (29,30). In one product, the dried film obtained from the formulation is soluble in the formulation, which includes low molecular weight, high acid polymers and a fairly large amount of ammonia (31). Repeated use does not contribute to a buildup of poHsh. 

There are numerous misconceptions about the sources of various chemical elements in waste, particularly those that are potential acid formers when the waste is incinerated or mechanically converted and used as a refuse-derived fuel. For example, it is often mistakenly stated that the source of chlorine in waste, hence a potential source of HCl emissions, is poly(vinyl chloride). The relative contents of selected, potentially acid-forming elements in the organic portion of a sample of waste collected from various households in one U.S. East Coast city is given in Table 2 (17). In this city, a chief source of chlorine in the waste is NaCl, probably from food waste. 

Sodium bisulfate, NaHSO, is a convenient mild acid and is safe for uses as a household toilet-bowl cleaner, automobile-radiator cleaner, and for swimming pool pH adjustment. It is used for metal pickling, as a dye-reducing agent, for soil disinfecting, and as a promoter in hardening certain types of cement. 

Acid cleaners based on sulfamic acid are used in a large variety of appHcations, eg, air-conditioning systems marine equipment, including salt water stills wells (water, oil, and gas) household equipment, eg, copper-ware, steam irons, humidifiers, dishwashers, toilet bowls, and brick and other masonry tartar removal of false teeth (50) dairy equipment, eg, pasteurizers, evaporators, preheaters, and storage tanks industrial boilers, condensers, heat exchangers, and preheaters food-processing equipment brewery equipment (see Beer) sugar evaporators and paper-mill equipment (see also Evaporation Metal surface treati nts Pulp). 

Specialty sulfonic acid-based surfactants make up a rather large portion of surfactant production in the United States. Approximately 136,000 metric tons of specialty sulfonic acid-based surfactants were produced in 1992, which included alpha-olefin sulfonates, sulfobetaines, sulfosuccinates, and alkyl diphenyl ether disulfonates (64). These materials found use in the areas of household cleaning products, cosmetics (qv), toiletries, emulsion polymerization, and agricultural chemical manufacture. 

A 5—6% sodium hypochlorite solution is sold for household purposes, of which the largest use is in laundry. Solutions of 10—15% NaOCl are sold for swimming pool disinfection, institutional laundries, and industrial purposes. Solutions of various strengths are used in household and industrial and institutional (I I) cleaners, disinfectants, and mildewcides. A small amount is used in textile mills. Sodium hypochlorite is also made on site with 30—40 g/L available chlorine for pulp bleaching, but its use is decreasing in order to reduce chloroform emissions (see Chlorine oxygen acids and salts). 

Besides the medicinally used herbal mixtures, there arc also the so-called household teas which are preferred by people who are sensitive to coffee or who do not wish to drink a caffeine-containing beverage on a regular basis. Household teas are made up from drugs which, apart from small amounts of tannins, have only aroma substances and possibly also plant acids bramble leaves, raspberry leaves, hibiscus flowers, hips and haws, and apple skins arc frequent components of such teas [4].

Acidic and basic household solutions. Many common household items, including vinegar, orange juice, and cola drinks, are acidic. In contrast baking soda and most detergents and cleaning agents are basic.
