Study Notes
Chemistry
Substances Used in Household Products
Cleaning supplies and household products often include harmful chemicals that can impact human health. Even products marketed as "green" or "natural" may contain problematic components. For instance, cleaning agents such as bleaches, dish detergents, oven cleaners, and drain cleaners frequently contain volatile organic compounds (VOCs), which emit fumes that can trigger respiratory issues, allergies, and headaches. Other examples of chemically laden products include paints, glues, and oils.
Substances in Food and Beverages
Food and beverages may contain numerous chemicals to preserve freshness, enhance flavor, or increase shelf life. Pesticides, artificial flavors, colors, and preservatives are commonly added to various consumables. Some of these substances, such as synthetic sweeteners like saccharin or sorbitol, are controversial due to potential health risks.
Effects of Substances on Health and Environment
Substances can have significant impacts on human health and the environment. For example, exposure to certain chemicals found in cleaning products, such as VOCs, has been linked to chronic respiratory problems, allergic reactions, and headaches. Additionally, studies suggest that these chemicals can exacerbate conditions like asthma and other respiratory illnesses. Furthermore, cleaning products containing VOCs and toxic substances can negatively affect wildlife and ecosystems when introduced into the environment through improper disposal.
Types of Substances
There are several categories of substances, each with unique properties and applications. These include acids, bases, salts, sugars, alcohols, gases, metals, nonmetals, and organometallic compounds. Acids and bases play crucial roles in neutralizing solutions, while salts serve as essential nutrients for plants and act as electrolytes in biological systems. Sugars offer energy sources for living organisms, while alcohols can act as solvents. Gases participate in combustion processes, and metals and nonmetals exhibit diverse physical and chemical properties.
Chemical Properties of Common Substances
Common substances exhibit specific chemical properties that determine their behavior and interactions. Elements can exist in different forms called isotopes, which possess varying numbers of neutrons. Compounds, formed from the combination of two or more elements, can have unique properties that make them suitable for various applications. For instance, saltwater is a compound composed of sodium ions and chlorine ions, which dissolve in water to form an electrolyte solution.
Preventing Harm from Cleaning and Household Products
To minimize exposure to harmful chemicals in cleaning products, it's essential to read labels before purchasing and follow instructions carefully during use. Opt for products with reduced amounts of VOCs, fragrances, irritants, and flammable ingredients. Avoid using air fresheners altogether, as they often contain potent chemicals. Proper ventilation and storage away from children and pets are also crucial precautions.
