Study Notes

Common Chemicals in Consumer Products

Sugar is a common chemical found in food products.
Carbonated water contains carbonic acid (H2CO3).
Sodium hydroxide (NaOH) is often used in household cleaning products.
Sodium hypochlorite (NaClO) is commonly found in bleach.
Isopropyl alcohol (C3H8O) is used in many disinfectants.

Household Cleaning Products: Overview

Household cleaning products can contain toxic or hazardous substances.

Components of Household Cleaning Products

Abrasives

Abrasives like pumice, quartz, and nylon meshes help remove dirt through friction.

Acids

Mild acids, such as vinegar and lemon juice, effectively remove hard-water stains.
Oxalic acid is a strong rust remover but is highly poisonous, often found in toilet cleaners.
Hydrochloric and sulfuric acids are used in diluted forms in some cleaning products.

Alkalies

Alkalies are soluble salts that emulsify dirt and grease for easier cleaning.
Mild example: Baking soda (sodium bicarbonate, NaHCO3).
Strong example: Sodium hydroxide (lye or caustic soda) is used in heavy-duty cleaners.

Bleaches

Chlorine is the most commonly used bleach, while non-chlorine alternatives are emerging due to safety concerns.

Detergents

Laundry detergents can also serve as household cleaners. Builders enhance their effectiveness by loosening oily dirt.

Sanitizers

Sanitizers reduce bacterial populations and are essential in kitchen and bathroom cleaning.

Spirit Solvents

Spirit solvents found in waxes remove oily dirt, similar to dry-cleaning fluids.

Components of Beverages

Water

Water comprises approximately 90% of most beverages and is typically purified through reverse osmosis.

Sugar and Sweeteners

Sugars in soft drinks range from 1% to 12%, enhancing flavor and sweetness.

Fruit Juices

Fruit juices are nutritious, containing sugars, organic acids, fiber, and antioxidants.

Acidity Regulators and Carbon Dioxide

Carbonation levels in soft drinks vary from 1.5 to 5 g/L.
Acidity regulators improve taste and enhance preservation.

Flavoring and Coloring

Flavorings and colorings enhance the appeal of beverages and are regulated by agencies like the FDA.
Colorings are categorized into natural, artificial, and caramel types.

Preservatives

Chemical preservatives increase the microbiological stability of beverages, selected based on the product's properties.
