Baking soda and vinegar foam, glue and borax putty and red cabbage pH indicator are all excellent reactions to create with household chemicals. They are also safe enough for children to explore.Know More
Baking soda, a base, and vinegar, an acid, fizz on contact with one another, producing carbon dioxide and water. The addition of liquid soap to the reaction traps the gas bubbles and forms foam.
White glue and borax react to form a malleable, putty-like material. White glue contains long chains of molecules, or polymers, of polyvinyl acetate. When mixed, the borate ions from the borax begin replacing acetate groups in the glue, forming links between the polymers to create a three dimensional structure. The result is soft solid that holds its shape for a short time.
The juice of red cabbage provides an excellent pH indicator for determining the presence of acids and bases. Boiling red cabbage in water for approximately 10 minutes yields a purple juice, the exact color of which depends upon the pH of the water. Acids such as vinegar or lemon juice cause the cabbage juice to turn a reddish color. Bases such as baking soda or ammonia cause shades of blue through green to form.Learn more about Solutions & Mixtures
Reactivity in science refers to how various chemicals participate in chemical reactions when they are exposed to other substances. A chemical that reacts easily with other substances is considered highly reactive.Full Answer >
According to Steve Spangler Science, mixing vinegar and baking soda starts a chemical reaction that produces carbon dioxide, or CO2, and water. The chemical names of the two ingredients are acetic acid, which is the vinegar, and sodium bicarbonate, which is the baking soda.Full Answer >
Acidic solutions turn litmus paper red, turn a universal indicator red or yellow, taste tart or sour, conduct electricity, react with metals, and neutralize bases. When an acid and a metal react, hydrogen is released; when an acid and a base react, an ionic compound called a salt is formed.Full Answer >
Caustic soda is an inorganic compound that is a metallic base neutralized by acidic substances. The chemical name for caustic soda is sodium hydroxide, and it has the chemical formula NaOH. It is also known as lye.Full Answer >
