CHEMICALS IN EVERYDAY LIFE OBJECTIVE The objective of this experiment is to aim observations regarding the reactions and properties of household ammonia and baking soda and explain the behavior of these two common household compounds. INTRODUCTION One of the simplest observations anyone can make about the world is that it is filled with “stuff”- tables, chairs, books, soil, plants, and animals including ourselves. The “stuff” that such objects are made of is called matter. Everything you see around you is made of matter. Matter is anything that has mass and volume. Our understanding of what defines a chemical element has changed radically since ancient times, but the basic concept of a fundamental kind of matter has endured. An element is a substance that cannot be separated into simpler substances by a chemical change. Today, slightly more than 100 chemical elements are known. When two or more elements combine in a chemical reaction, they form a compound. A compound is a substance that contains two or more elements combined in a fixed proportion. Many objects that appear at first glance to be made of a single kind of matter turn out to be a mixture. A mixture is a blend of two or more pure substances. Not all mixtures appear in the first glance to be made of a single kind of matter. Sometimes, as in the case of salad dressings, you can see the different parts of a mixture. A mixture that has visible different parts is called a heterogeneous mixture. Other mixtures do not contain visibly different parts. Such mixtures are called homogeneous mixture. Homogeneous mixtures are also called solutions. At home, such elements, compounds and mixtures can be found. Some are not common but for a long run, we do meet them. The two common compounds used at home are household ammonia and baking soda.
